Oliver noted this, too (most of his examples should in principle do
something sensible eventually but I haven't got round to that level of
detail yet).  I think it doesn't matter that much if either this gets
silently turned into x=("string"), or if there's an error on the x
assignment, as long as we pick one and document it.

Well, we don't have that syntax, but this should work:

  typeset -A hash=(bob robert bill william)

but doesn't because of a bug fixed below.  If you're playing along at
home --- this is exclusive to the typeset-array branch.
