When I wrote about this todo a while ago, I suggested that assigning to a lexical was enough to indicate that it was used. For example, "my $exit = Scope::Guard->..." is useful, even if you don't mention $exit again. Similarly, "my ($self, @x) = @_" is not madness. This does mean that we're detecting fewer actually bogus cases. We'd only get variables declared and use never, rather than used once. (my $x;) Is that sufficiently useful to pursue? I'm not sure. --- via perlbug: queue: perl5 status: open https://rt.perl.org:443/rt3/Ticket/Display.html?id=5087Thread Next
