Hello.
I wonder how does the type system (without -rectypes)
check cyclic type abbreviations.
The type system with -rectypes can tell between
type 'a t = A of 'a
type s = s t
and
type 'a t = 'a
type s = s t
It admit the former, but the latter.
But, the type system without -rectypes cannot tell them.
Why?
I thought that the former would be legal without -rectypes.
Regards,
Keiko NAKATA.
