unfortunately there is no macro mechanism in pure Perl.

Technically, there is. Although using source code filters is not a good idea, it's basically a smarter version of C makros.

perl -e 'use Crypt::Digest::SHA256 qw[sha256_hex]; print substr(sha256_hex("the Answer To Life, The Universe And Everything"), 6, 2), "\n";'
