Title: Regular expressions & prop to bring back a better `String::has(Pattern)`

As asked by everyone...

I'll be waiting after the test to make sure that it doesn't break anything.

What do you think of the doc/tests on the protected methods? I don't have any info to add, only tests and `requires`.

The only TODO would be to implement subexpressions; to get the the substrings of the parenthetical subexpressions of a single match. It is not the most common use but could be useful in some compilers.
