I agree this is a big shortcoming of Arcade. I am hard pressed to think of another scripting language that doesn't support, at least partially, regular expressions.

Just evaluating a regex for use in constraint rules would be great, or to extract particular substrings from input text (classic example would be an email or a phone number).
