Hello again,

I also have an issue with the func 'match': instead of simply trying to mat=
ch and fail if not found, it seems to search for a matching snippet all alo=
ng the source: what a method 'find' or 'search' usually does, as opposed to=
 'match' precisely. Thus, i'm forced to prefix all regex patterns with '^'.
What am I missing?
(If I'm not missing anything, would be useful to have match vs find, don't =
you think?)

If you want your regular expression which matches at the begging of the string
you use ^ (carrot). A regex is for describing what it takes to make a match, if
your regex doesn't use this than it can match anywhere in the string. So to me
having a match and find is redundant. I mean what does find do when you have ^
and $ surrounding the expression?
