in reply to looking for a good idiom: return this if this is true

if you wouldn't mind refactoring thatroutine, this works:

sub thatroutine(\$) { # do something to ${$_[0]} } sub thisroutine { return $_ if thatroutine local $_; ... my $namedvar; return $namedvar if thatroutine $namedvar; }
Ugly as hell but it appears to work.

[Corion]: So maybe I should investigate how to plug in a cache in front of DBIx::Class so I can do a ->selectall_hashre f and then satisfy the "sub"-selects from that cached single SELECT statement ...
