Hello PerlMonks,

I need your help to understand how to use a hash value as a subroutine name while "strict ref" is in use-

use strict;

my $code_ref = {'SUM', 'sum'};
sub sum($$){...}

($codes->{'SUM'})->(4,5);

[download]

Result: gives an error -

Can't use string ("sum") as a subroutine ref while "strict refs" in use at ...

Thanks.
