Yes, I just remembered that I'd read that comment (while watering my plants)
and wondered it if was it.
This part of Exporter.t is currently bogus:
my $warnings;
BEGIN {
$SIG{__WARN__} = sub { $warnings = join '', @_ };
package Testing::Unused::Vars;
@ISA = qw(Exporter);
@EXPORT = qw(this $TODO that);
package Foo;
Testing::Unused::Vars->import;
}
::ok( !$warnings, 'Unused variables can be exported without warning' ) ||
print "# $warnings\n";
(because the test C<require>s Exporter, rather than C<use>ing it)
Should we fix Exporter not to warn? Rather than relying on "performance hack"
to keep it quiet?
