Review comment:
`Expect a type` -> `Expect a GenericPtrType` maybe be better

there is a `transform_TypeTuple` impl that may be useful here

This seems to be a bug fix right?

Review comment:
mismatch between the code and comment here. BTW is this check necessary
here?

Review comment:
Does this for-loop imply that all params of `TypeApply` call will be
transformed into `GenericPtrType`? If so can we specify that here as well
instead of `ty.TypeGeneric`

Use of `GenericPtrType` here maybe more accurate

Review comment:
I thought this change only impact `GenericPtrType` instead of
`ConcreteType` here. Is that the case?
