Have you considered adding a C<map> example to RFC 31? Yield would add
multiple output items per input item better IMO than the current practice
of accumulating a list of output items and returning it at the end.
%newhash = map {yield $_; transform $somehash{$_}} @keysubset;
isn't any better than
%newhash = map {($_,transform $somehash{$_})} @keysubset;
but you can certainly come up with a reasonable example. Listing inventories
by department, for instance. By yielding we would save the creation of the
per-iteration temporary and push directly onto the result.
