The old code is clearly unusable for some characters in the key, so a
change of some sort is warranted.

All that occurred to me was an additional option to provoke an extra
expansion step on the argument after locating the brackets.

  unset -? 'hash[$i]'

would then be reliable.  If the extra backslash stripping occurred early
enough it wouldn't get in the way.
