This is a non issue for anything other than a limited type. You can
name your constructors whatever you want, they can take any number of
parameters and there can be any number of them.
For limited types, the only way around this is to hide them behind
access types for them. Then things again work just fine - except for
storage management issues. Hence, the need for GC. Limited types are
really extremely useful. Unfortunately, much of this is lost without
GC support.
