I'm trying to think of some application where you'd reasonably need to accommodate random substitutions with possible /g modifiers but I'm coming up blank (but probably need more caffeine to boot . . .). I started to post something mentioning string eval (which as has been pointed out isn't the answer there either) but something about the original question has a not-too-faint whiff of "XY problem" about it.

Could you step back a hair more and explain why you think you need to run substitutions with arbitrary modifier flags? It may be that you don't actually and you could really get by with one of the prior suggestions (like moving compatible flags onto the front of the pattern). Or maybe you could work with some sort of (handwaving vigorously here) plugin / module system where you write substitution classes which implement a specific role that . . . /shrug
