OK, thats a reasonable definition for enumerations, but its missing the
non-ionteger eqivalent, "scale points" or whatever you want to callthem,
eg in ringmod_2i1o(1188) "Modulation depth (0=none, 1=AM, 2=RM)" input,
control, 0 to 2, default 0. its not an integer control, its a continuous
valued control with specific meanings at specific points. Another example
is an oscilator control knob in LFO modules with contiunous varition
through sine, tri, saw, square.
I'l grant you that this case is less common, but its still one of the
"neccesary" control types.

Right, in the integer hint case I dont see why you would.
I dont think what you're prosoing is an unacceptably bad hack (though I
dont think its a good one either), but I do think the RDF solution is
much cleaner.
