Re: Pure perl lexical sub import

If you don't want to take code from Exporter, you can do it like this:

BEGIN {
    *looks_like_number = \&Scalar::Util::looks_like_number;
}
[download]

#!perl
use 5.020;

use Scalar::Util ();

BEGIN {
    *looks_like_number = \&Scalar::Util::looks_like_number;
}

say looks_like_number(42);
