Use real regexes for checking

[JJ]

Right now it's tricky, since strings are rexified; it's probably better to add new features for checking real regexes. You can code alternatives into regexes, so using several ones might not be it.

Thanks for making this github action!

Just wondering if you rexify by escaping: 6f56b9f

Could you just "reverse" the meaning of the escape?

so \s\* would be the original regex \s*

Assuming that would be okay, you could just process the expression twice.

["(", ")", "[", "]", "?", "+", "*"].forEach((s) => {
  expression = expression.replace(s, `\\${s}`);
});
["\\\\(", "\\\\)", "\\\\[", "\\\\]", "\\\\?", "\\\\+", "\\\\*"].forEach((s) => {
  expression = expression.replace(s, `${s.slice(-1)}`);
});
return new RegExp(expression);

Thanks for the suggestion. I drew myself into a corner here. I think that the solution will rather be to use a different parameter for regexes, so that it keeps compatibility, maybe together with a deprecation cycle.
