Fully ditching the currently used API is probably too much.

A possible idea:
regex("blah") <<== repeat over the whole input. 
regex("blah","") <<== repeat over the whole input. 
regex("blah","g") <<== repeat over the whole input. 
regex("blah","d") <<== doesn't repeat over the whole input.


So far you have done good work on the regular expression implementation, so I
trust your work. Thank you.
