In Python, you would probably use regex for the pattern matching. In SPITBOL, you can accomplish the task at the language level. I doubt the pattern matching is as capable as regex but that's a useful feature to have (edit: based on braythwayt's comment, it sounds like the pattern matching is more capable than regex). It might be better suited to NLP tasks. According to the developer, "SPITBOL is unique in the power it provides to manipulate strings and text. I’ve yet to see anything else come close."

See Zuider's comment for more information.

I hope all-caps-keywords is optional.
