Hi,
I started to implement Generics.Collections in FreePascal
(successfully!). I wanted to start using objfpc, but I have a problem
with generics in fpcobj mode. In Delphi mode i don't have any problems
with my implementation. For example:
type
IEnumerable = interface
end;
IEnumerable<T> = interface
end;
IEnumerable<T1, T2> = interface
end;
in fpcobj:
type
IEnumerable = interface
// ? generic IEnumerable<> = interface
end;
generic IEnumerable<T> = interface // Error: Duplicate identifier
"IEnumerable$1"
end;
generic IEnumerable<T1, T2> = interface // Error: Duplicate
identifier "IEnumerable$2"
end;
I think it is a big problem... Especially for future usage of
anonymous methods (when/if they are implemented)... Example from
Delphi:
This is by design to allow backwards compatiblity with older generic
code. Maybe I'll add a modeswitch somewhen though to allow this in mode
ObjFPC as well...
Regards,
Sven
