Re: [sv-ec] random resizing of associative array

I don't think that it makes sense to create entries in an
associative array as 13.4.7 suggests.  For dynamic arrays,
the indices are constrained to the range 0..N so just
specifying a size is sufficient.  I think that if you want
a randomly sized and/or randomly indexed associative array
that you need to first construct the "shape" and then
randomize the elements.
