I've attached patch to mantis bug which makes compiler print error
about missing operator "TPar" = "TPar". This could, at least, give
user some hint about what is wrong.
The proper solution for this problem is not simple. Somehow, you will
have to make operator = (const A, B: TPar) visible inside FGL unit
(because of the way generics are currently implemented), or make
compiler think that TPGList is implemented in the place where
specialization occurs (so compiler first searches "specialization
space", and after that "generic-declaration space").
