in reply to Sub ref from string without eval

If you know which package you expect your subroutine to be in you might also be able to use the functionality of UNIVERSAL::can

use strict; use warnings; sub Foo { warn 'foo'} my $x = 'Foo'; my $sub_ref = main->can($x); $sub_ref->();

    Which is generalized even better as:

    my $sub_ref = __PACKAGE__->can($x);

    my @a=qw(random brilliant braindead); print $a[rand(@a)];
