普通人应该关注哪些方面？

对于普通读者而言，建议重点关注what’s new in the rust version is that these syntactic forms are now supported. (?=.*a)(?=.*b)(?=.*c)def is semantically equivalent to def(?=.*a)(?=.*b)(?=.*c) since the lookahead bodies are unrelated to def, but the first form doesn’t fit the (?<=R1)R2(?=R3) lookaround normal form that the dotnet version requires, so its parser rejects it. same goes for lookaheads inside union branches - something like (a(?=x)|b(?=y)|c(?=z)) where each alternative has its own lookahead condition is perfectly valid but doesn’t normalize into a single R2(?=R3). the rust version handles all of these.
