Regex benchmark compile error

[Extra-Creativity]

I find a small benchmark to compare regex performance in different languages, and I'm trying to test it on this project. But this regex that is used to match Email seems not to compile:

R"([\w.+-]+@[\w.-]+\.[\w.-]+)"

Is this a bug?

you need to escape the dash inside character classes: [\w.+\-]+@[\w.\-]+\.[\w.\-]+ It's a consequence of CTRE's parser design and also my decision to not have "special" weird cases. In CTRE dash inside character class always needs A-B to mark range. If it's meant as a character, you need to escape it.
