True. Would anyone mourn @$scalar_containing_variable_name if it died?
I've never used it, and I'm rather glad I haven't. Perl5's -w doesn't
notice $x="var"; print @$x either -- it'll complain if you mention @var

My code for doing what I thought Exporter did is:
sub import {
my $p = caller(1);
*{"${p}::E"} = \%{"${p}::E"};
}
but that doesn't run afoul of use strict 'refs'. Can you point me to the
passage in Exporter.pm that uses this?
It does run afoul of use strict
Thanks! Ok, from a type inferencing perspective...

Symbolic references are used for dynamic function generation:
foreach my $func (qw(red green blue)) {
*$func = sub { "FONT COLOR=$func@_/FONT" }

Probably have to punt on checking user code in a main
