Add a regex match function for data validation

I would love it if Airtable had a formula to determine whether a string (or field reference containing a string) matched a given regular expression.

Google Sheets, for example, has the REGEXMATCH() function. It takes a string/cell reference and a regex, and returns TRUE or FALSE based on whether a match is found.

This would be immeasurably useful. A couple ideas:

Some of these are possible now with complicated sequences of FIND, LEFT, MID, RIGHT, and LEN. It’s hard to debug formulas built this way, however. Regex is compact, easy to test, and comparatively easier to read.
