I am wondering if this might be causing problems or unnecessary
resolutions. For instance, at least for languages such as Ada,
you don't really need to resolve the pointer type's target type
when just trying to print the pointer's value. In my experience,
this is the type of thing that should be done at type/value printing
time, or when dereferencing the pointer (Eg. during expression
evaluation).
