		Ref	d2 )

Are d1 and d2 α-equivalent?

In infer mode, type inference is happening and Infers will be resolved, if possible. Also, two free but different Vars are considered α-equivalent.
When **not* in infer mode, no type inference is happening and Infers will not be touched. Also, Two free but different Vars are not considered α-equivalent.

◆ assignable()

		Ref	value )

inlinestatic

Can value be assigned to sth of type?

Note: This is different from equiv(type, value->type()) since type may be dependent.
