PseudoObjectExpr - An expression which accesses a pseudo-object l-value. A pseudo-object is an abstract object, accesses to which are translated to calls. The pseudo-object expression has a syntactic form, which shows how the expression was actually written in the source code, and a semantic form, which is a series of expressions to be executed in order which detail how the operation is actually evaluated. Optionally, one of the semantic forms may also provide a result value for the expression.
If any of the semantic-form expressions is an OpaqueValueExpr, that OVE is required to have a source expression, and it is bound to the result of that source expression. Such OVEs may appear only in subsequent semantic-form expressions and as sub-expressions of the syntactic form.
PseudoObjectExpr should be used only when an operation can be usefully described in terms of fairly simple rewrite rules on objects and functions that are meant to be used by end-developers. For example, under the Itanium ABI, dynamic casts are implemented as a call to a runtime function called __dynamic_cast; using this class to describe that would be inappropriate because that call is not really part of the user-visible semantics, and instead the cast is properly reflected in the AST and IR-generation has been taught to generate the call as necessary. In contrast, an Objective-C property access is semantically defined to be equivalent to a particular message send, and this is very much part of the user model. The name of this class encourages this modelling design.
