Don't forget to check the post of Ondrej.
Personally, I think using 'as' to convert an integer to an enum with range
check is still the best approach. It does not require new intrinsics (far
too many of those already) and does what it says. To simply check if an
integer is a valid enum, I think 'is' would be equally suitable.

I don't recall a conversation where such an intrinsic is seen as
desirable, but if such a construct is desirable, then that's a good thing
since it will help patch up this problem.
As for the Delphi problem, it's second-hand information I heard from a
friend who uses Delphi at work and something about not handling
out-of-range enumerations was a deal-breaker from not using FPC. I may
have some details wrong though. But all that side, would development of
an intrinsic be an acceptable solution, and what name are we going for?
(One has to be careful we don't break existing code if possible)
