The only mention of backtrack is : bmatch
it returns a regex object with a machine state, and last match, 
but it is still not telling me how to actually do a backtrack 
match. I.e. if i know the machine state and a match (in my 
example, does that mean that foo is returned as a match or does 
it mean thatbaz /bar is returned as a match, and the next attempt 
will match the bar/baz - if not, then what is the call sequence? 
bmatch (match bar/baz) then match FOO, then again try to match 
what bmatch returned?)
