These should both behave the same. Did you see this cause a problem somewhere?

My mistake. I was working in the Scala interactive shell while reading through this code. I tried to split a string on "." and "blah.blah".split(".") does not appear to behave the same as "blah.blah".split('.'). I assumed it was the difference between "." being a String and '.' being a Char. I feel stupid now for not actually trying it with "/" before submitting this. ;)

ah, yeah, the string version is interpreted as a regex. (this API comes from java.) so "." means single-char wildcard in that context. :)
