Imports

Expr	Provides all expression classes.
Variable	Provides classes for variables, such as fields, parameters, local variables, and constants.

Classes

Access	An access expression. Either a `this` access (`ThisAccess`), a `base` access (`BaseAccess`), a member access (`MemberAccess`), an assignable access (`AssignableAccess`), or a callable access (`CallableAccess`).
ArrayAccess	An access to an array, for example the access to `args` on line 3 in
ArrayRead	An access to an array that reads the underlying value, for example the access to `a` on line 2 in
ArrayWrite	An access to an array that updates the underlying value, for example the access to `a` on line 2 in
AssignableAccess	An assignable access, that is, an access that is valid on the left-hand side of some assignment. Either an access to a variable (`VariableAccess`), an access to a property (`PropertyAccess`), an access to an element (`ElementAccess`), an access to an event (`EventAccess`), or a dynamic member access (`DynamicMemberAccess`).
BaseAccess	A `base` access, for example `base` on line 2 in
CallableAccess	An access to a callable. Either a method access (`MethodAccess`) or a local function access (`LocalFunctionAccess`).
ElementAccess	An access to an element. Either an access to an indexer (`IndexerAccess`), an access to an array (`ArrayAccess`), or a dynamic element access (`DynamicElementAccess`).
ElementRead	An access to an element that reads the underlying value. Either an access to an indexer (`IndexerRead`), an access to an array (`ArrayRead`), or an access to a dynamic element (`DynamicElementRead`).
ElementWrite	An access to an element that updates the underlying value. Either an access to an indexer (`IndexerWrite`), an access to an array (`ArrayWrite`), or an access to a dynamic element (`DynamicElementWrite`).
EventAccess	An access to an event, for example the accesses to `Click` on lines 7 and 8 in
EventAccessExpr	An internal helper class to share logic between `EventAccess` and `EventCall`.
EventRead	An access to an event that reads the underlying value, for example the accesses to `Click` on lines 7 and 8 in
EventWrite	An access to an event that updates the underlying value, for example the access to `Click` on line 7 in
FieldAccess	An access to a field, for example the access to `F` on line 5 in
FieldRead	An access to a field that reads the underlying value, for example the access to `F` on line 5 in
FieldWrite	An access to a field that updates the underlying value, for example the access to `F` on line 5 in
IndexerAccess	An access to an indexer, for example the access to `c` on line 5 in
IndexerAccessExpr	An internal helper class to share logic between `IndexerAccess` and `IndexerCall`.
IndexerRead	An access to an indexer that reads the underlying value, for example the access to `c` on line 5 in

LocalScopeVariableAccess	An access to a local scope variable. Either an access to a parameter (`ParameterAccess`) or an access to a local variable (`LocalVariableAccess`).
LocalScopeVariableRead	An access to a local scope variable that reads the underlying value. Either an access to a parameter (`ParameterRead`) or an access to a local variable (`LocalVariableRead`).
LocalScopeVariableWrite	An access to a local scope variable that updates the underlying value. Either an access to a parameter (`ParameterWrite`) or an access to a local variable (`LocalVariableWrite`).
LocalVariableAccess	An access to a local variable, for example the access to `x` on line 3 in
LocalVariableRead	An access to a local variable that reads the underlying value, for example the access to `x` on line 3 in
LocalVariableWrite	An access to a local variable that updates the underlying value, for example the access to `x` on line 3 in
MemberAccess	A member access. Either an access to a field (`FieldAccess`), an access to a property (`PropertyAccess`), an access to an indexer (`IndexerAccess`), an access to an event (`EventAccess`), an access to a method (`MethodAccess`), an access to a type (`TypeAccess`), or a dynamic member access (`DynamicMemberAccess`).
MemberConstantAccess	An access to a member (field), for example the access to `F` on line 5 in
MethodAccess	An access to a method, for example the access to `Filter` on line 5 in
NamespaceAccess	An access to a namespace, for example `System` in `nameof(System)`.
ParameterAccess	An access to a parameter, for example the access to `p` on line 2 in
ParameterRead	An access to a parameter that reads the underlying value, for example the access to `p` on line 2 in
