Useful compilation, but you can go back and reenable strict 'refs'.

#!/usr/bin/perl -w
use strict;

for (qw(foo bar)) {
        ($main::{$_} or sub { print "No such sub: $_\n" })->();
}

sub foo {
        print "Yes, I'm here.\n";
}
__END__
Yes, I'm here.
No such sub: bar

Alternatively: (UNIVERSAL::can('main', $sub) or sub { print "No such sub: $_\n" })->(); ____________
