Ooh, nice! That's eminently readable. Much more likely to survive a code review than aristotle's ex-bang-bang operator.

Rather than

my @part = ( 'http://example.net/app', ( 'admin' ) x!! $is_admin_link, ( $subsite ) x!! defined $subsite, $mode, ( $id ) x!! defined $id, ( $submode ) x!! defined $submode, );

we would now have

my @part = ( 'http://example.net/app', grep( $is_admin_link. 'admin' ), grep( defined($subsite), $subsite ), $mode, grep( defined($id), $id ), grep( defined($submode), $submode ), );

I like it.
