One possibility to make progress would be to keep !( but allow omitting 
the parens when only one argument is being passed. That way many 
instantiations will be helped. For example, in wake of the impending 
demise of complex built-ins:

Complex!double alpha;
Complex!float[] data;

That way, again, we leverage the fact that an extra symbol is needed 
instead of compulsively requiring it in addition of the parens.

One nice thing about this change is that it keeps all code as it is, 
just lifts one restriction.

How about that?
