Keep in mind that $parameters was created specifically to support
completion and to provide a way to get a list of parameters that are
applicable to a particular context. Mostly you shouldn't need to care
whether something is a nameref to a whatever or just a plain whatever.
I don't particularly object to the value including "nameref" but the
rest of the type is needed.

Extracting existing uses of _parameters -g we have:

  ^a*
  a*
  *array*
  array
  *array*~*readonly*
  *assoc*
  *association*~*readonly*
  *export*
  *export*~*readonly*
  (integer|float)*
  ^*readonly*
  ^*(readonly|association)*
  *scalar*
  scalar*export*

A few of those probably need an initial *.
