Not exactly because I have something against the original proposal of PREG_THROW_..., but because your suggestion can (possibly?) increase performance for those apps who use regexps a lot.

Since people have been using regexps in PHP for ages in a way they are, I believe it should be possible to make an instance of CompiledRegex from a usual pattern-string. In my practice, I don't use many different modifiers, but those which I do use often (mostly "i" and "s") - I type them automatically when writing a pattern. Like a muscle-memory. In other words, it is easier for me to still input them as part of the pattern that supplying them as parameters. Besides, such a possibility will simplify the process of migration to this class and possible future API: you just copy an existing pattern without bothering to extract the modifiers from it.
