I don't want to introduce a name for the return value to allow things like
if(node.getName.equals("retval")) {
ReturnValueDescriptor descriptor = (ReturnValueDescriptor) node.getElementDescriptor();
}
The actual type of a node is still given by it ElementDescriptor. The name cannot be used
for that. It is more for convenience
and "nice" toString implementation. Yes it could be ambiguous, but I don't
think it matters. Any code relying on the property path
as string is potentially wrong anyways. A white space seems odd, especially in the light
of toString.
In that light $retval might be a legal java identifier, but chances are slim someone uses
it.

What if there is a property or method called "returnValue"?
I think the constant string returned should contain a character that is not legal for java
identifier names. E.g. a white space.

Another obvious option would be "returnValue". Having a standardized node name
for return value nodes would also help with better toString() implementations for j.v.Path
(although that's not standardized).
