Class DataFlow::PostUpdateNode

A node associated with an object after an operation that might have changed its state.

This can be either the argument to a callable after the callable returns (which might have mutated the argument), or the qualifier of a field after an update to the field.

Nodes corresponding to AST elements, for example ExprNode, usually refer to the value before the update.
