What’s nostalgic to me is that this is such a classic Perl pattern: hashing manipulated strings to find relationships. Prior to Perl doing this was painful. Boost wasn’t a thing. Python was in its cradle and Java was still struggling with beans. Perl removed the barriers between complex coding ideas and an implementation that C wasn’t ready for. The time from thought to prototype was near instant compared to current compiled languages.
