The definition of "_.F" in 134_functor2.sml and the use of it in
134_funtor.sml have different types.
After record compilation:
134_functor2.sml:
val _.F(9)
: ['a,
'b.
{TAG('a), SIZE('a), TAG('b), SIZE('b)}
-> ('a * 'b -> 'a * 'b) -> {'a, 'b} -> {1: unit(t7[]) -> 'a * 'b}] =
(****** 'a denotes t1, 'b denotes t2 ******) ^^^^^^^^
...
134_functor.sml:
val $T_a(9) : {1: unit(t7[]) -> t1(t0[]) * t2(t5[])} =
(_cast(_.F)
: ['a,
'b.
{TAG('a), SIZE('a), TAG('b), SIZE('b)}
-> ('a * 'b -> 'a * 'b) -> {'b, 'a} -> {1: unit(t7[]) -> 'b * 'a}])
(****** 'a denotes t2, 'b denotes t1 ******) ^^^^^^^
{t2(t5[]), t1(t0[])}
{_tagof(t2(t5[])), _sizeof(t2(t5[])), _tagof(t1(t0[])), _sizeof(t1(t0[]))}
...

This is a bug in name evaluator; if the parameter signature in
functor definition and functor application are different in
declaration order, then types are not properly passed.
I took the order of lifted type variables according the order
on the path of original type names.
