> In Lua it's only the start/end of the string

There's an additional caveat: if you use the optional "init" parameter to specify an offset into the string to start matching, the ^ anchor will match at that offset, which may or may not be what you expect.

That is a good point, and something I've actually (personally) used quite a bit when writing parsers

I find it hard to imagine any other expectation passing the rubber duck test.

"Oh, so you expected the match to always fail, no matter what the string was?"

Well, it's not a completely outlandish scenario that the value of `init` might come from a variable that is sometimes at the start of the string and sometimes not, and a newcomer might expect `^` to only match when it is.

Don't get me wrong, it's certainly far more useful as it is, I'm glad it works this way.
