I don't have a solution for you at hand (but I hope that you'll find one 
:) ), but I have a suggestion: please include the main program file as 
well. In Delphi this is a bit ignored at least when I tested the new 
RTTI once (enumerating all classes, records in a program)...

Basically it works already, but I still need solve the corner case when 
one declares a constant, variable or function that has the same name as 
a generic. Also inline generics are a bit fragil. If I could work on it 
full power (means: train ride to Munich + train ride from Munich + maybe 
work at home), I believe I could have them in one or two weeks, but I 
additionally need to work on my bachelor thesis, so I can't stick to any 
ETA :(
