Fellow Monks, I humbly bring before you a piece of code that I have been looking at for about the past hour:

    foreach my $f (@fields) {
        push(@where, qq($f='$fromQuery::{ $f }'))
            if $fromQuery::{ $f };
        push(@searchString, qq($f=).escape($fromQuery::{ $f }))
            if $fromQuery::{ $f };
    }

What I'm trying to do is interpolate $f into $fromQuery::$f so that we end up with $fromQuery:foo if $fromQuery::foo exists. Does anyone know how this could best be handled?

As an aside, the fromQuery namespace comes from the CGI::import_names object method but that's not really that important.
