I think I overacted. I've seen too many people claiming that map{}
makes for hard to read code where the whole problem was that they
were unable to stop thinking in C. To me, with some background in
functional languages, map{} feels natural. Just like regexps.
Which is good when coding, but sometimes not so good when trying to
help people.

I see. Well I'd probably get a little lost in all those braces for a
second so
map {
$gen->user( {id => $ref->{$_}}, $_)
} keys %{$ref}
would probably be better. And the reason why I might stop for a
second is that Perl uses {} for both blocks and hashes. Which is
understandable with the limited list of bracelike characters, but
still sometime requires a bit too much context when parsing.
