Oh macro_rules are something I haven't dug into and explored much yet! Definitely used the built in ones, but haven't written any yet.
Thanks for the example!

I was intimidated by them for a while and avoided the topic - tried one once and now they even end up in my daily puzzle solutions :P Truly not complicated to use, and super handy!
