Yes, I didn't clearly understand the generic mechanism in fpc/tfpgmap.
I've read, `A class can be seen as a pointer to an object, or a pointer to a
record, with methods associated with it.' in fpc reference.pdf, chapter 6 -
Classes. Hence I think fpc takes object as pointer when specialize tfpgmap
template.
Now I catch your idea. The specialization of tfpgmap is similar to std::map in C++
(must define a (bool operator<(ref to another obj)const) function for the KEY
class).
I'll read the source code of unit fgl to deepen understanding.
Thank you very much.

I’m not quite getting what you’re trying to say… Free Pascal and Delphi
do have distinct syntaxes for generic type definition and
specialization. You may want to consult respective documentations to
clarify your understanding of the code.

Hope it helps.
