Well asking without giving yourself some data make it irrelevant but : http://en.wikipedia.org/wiki/Pattern_matching http://www.tbray.org/ongoing/When/200x/2007/09/21/Erlang and other on the web. Also did yoi-u really try to do the same in erlang compatred to pattern matching ? > > If you're going to allow this kind of pattern matching, I would use regexps > until it was proven inefficient. > Pattern matching is more efficient in erlang. Why would would you use regexp where it's not needed. regexp give an extra level of complexity we don't need here.
