I think it is possible but solution proposed by Sven is good enough :). As
was mentioned in my previous message to Sven:

100% agree I don't have problem with a little Delphi incompatible RTTI, the
bigger picture is more important than small details, but quote from Jonas
Maebe ([fpc-devel] Attributes
 thread): "some people wanted it to be Delphi compatible, other people did
not mind if it was not. Both categories of people were in the core team."

Delphi incompatible info was mentioned as serious problem for merging RTTI
branch into trunk.

Glad to hear that. RTTI together with closures is "must to have" feature.
Extended RTTI + closures is the last missing element for many users to
escape from Delphi.
