There are lots of kinds of special variables besides just colon-arrays.
Most of them involve more special handling than just changing the set/get 
functions for the values.  On further inspection I now understand that
colonarr{set,get}fn are assuming that there's a global char ** somewhere
(pointed to by the param struct) in which to store the associated array
representation, so it's not merely a matter of changing the functions
even for this case.

vared works a lot better on colon-arrays (scalars) than on true arrays.

I'm not (at this point) suggesting changing any syntax other than to
add something to typeset.
