Class Expr
An expression. Either an access (Access), a call (Call), an object or
collection initializer (ObjectOrCollectionInitializer), a delegate
creation (DelegateCreation), an array initializer (ArrayInitializer), an
array creation (ArrayCreation), an anonymous function
(AnonymousFunctionExpr), a local variable declaration
(LocalVariableDeclExpr), an operation (Operation), a parenthesized
expression (ParenthesizedExpr), a checked expression (CheckedExpr), an
unchecked expression (UncheckedExpr), an is expression (IsExpr), an
as expression (AsExpr), a cast (CastExpr), a typeof expression
(TypeofExpr), a default expression (DefaultValueExpr), an await
expression (AwaitExpr), a nameof expression (NameOfExpr), an
interpolated string (InterpolatedStringExpr), a qualifiable expression
(QualifiableExpr), or a literal (Literal).
