I looked at the archives, but didn't find what I want.  How do I convert this fragment into Ruby?

    ($var1, $var2, $var3) = split(":");

I might also make note that Ruby is actually LESS free-form than Perl - Perl uses ";" as a command terminator; Ruby uses newlines!  So you can't have a multi-line statement without some kind of "continuation" marker, as much as I can tell.
