This seems like the perfect opportunity to introduce those unfamiliar to Robert Elder. He makes cool YouTube[0] and blog content[1] and has a series on regular expressions[2] and does some quite deep dives into the differing behaviour of the different tools that implement the various versions.

His latest on the topic is cool too: https://www.youtube.com/watch?v=ys7yUyyQA-Y

He's has quite a lot of content that HN folks might be interested in I think, like the reality and woes of consulting[3]
