Detailed Description

An identifier referring to a method name, along with an instance for the call. This is an intermediate value: MethodReferences are always eventually replaced by FunctionCalls in valid programs.

Method calls are only supported on effect-child types, and they all resolve to intrinsics prefixed with '$', and taking the 'self' object as the last parameter. For example:

uniform shader child; ... child.eval(xy) --> $eval(xy, child)
