This is caused by the problem in the for-to loop:
for ch := Low(T) to High(T) do
WriteLn(ch)
How should I solve the problem in the for-in loop?
I tried the next way:

You can use the rtti generated for those enums.
For me it is still the question if for-to loop should work:
for ch := Low(T) to High(T) do
WriteLn(ch)

Delphi compiler does not support for-in loop for types (enums, integer,
...). This is fpc extension :)

No. I know delphi allows to enumerate multidimensional arrays but fpc

But it fails the same way.
ch := succ(ch);
OTOH, I am not sure -- obviously either Succ or Inc is buggy, but which one?
Maybe runtime instead of compile-time error is actually correct?
