Let's see:

auto s = "abcabcabab";
auto result = find(s, RegExp("b"));

becomes:

auto s = "abcabcabab";
auto result = match(s, Regex("b")).pre.length;

They return different things on no match, but I think the latter is 
better (pre returns the whole string on failure, which makes sense and 
is easier to compose).

rfind has no simple equivalent so it should probably be added. On crazy 
thought would be to have a primitive to reverse a Regex. Then you can 
search the reversed string for the reversed regex.

search adds no functionality over match.

Yah, never liked inPattern.
