This idea makes me nervous. Partly because I think we should keep the set of semantic changes between non-module code and module code reasonable small, and partly because the idea of your proposal is to continue to treat strings as sequences of 16-bit code units, not Unicode code points-- which means that quietly switching regexps to be closer to operating at the level of code points seems like it creates a kind of impedance mismatch. It feels more appropriate to me to require programmers to declare explicitly that they're dealing with a string at the level of code points, using the (quite concise) /u flag. That way they're saying "yes, I know this string is just a sequence of 16-bit code points, but it may contain non-BMP data, and I would like to match its contents with a regexp that deals with code points." (Again, I'm still new to the finer points of Unicode, so I'm prepared to be shown I'm thinking about it wrong.)
