Hell, you can even use regex to search your stash in Path of Exile 2.

Absolutely, the syntax is difficult to remember, but knowing about concepts like lookaheads etc. is already far beyond what “regex is line noise” coders will ever achieve.

Regular expressions are not that difficult and coders that refuse to learn them because they “look like line noise” are terrible at their jobs.

I guess you’re right.
