You're right.  I rarely split on anything other than commas or 
semicolons. Here is a version that seems to handle the perl examples I 
could find and was a little shorter than other samples I saw:

   function strsplit(s, delim)
     local t = {}
     local pat = "(.-)" .. delim .. "(.+)"
     local c1, c2
     repeat
       c1, c2 = string.match(s, pat)
       t[#t+1] = c1 or s
       s = c2
     until c1 == nil
     return t
     end

Not that this whole thing was really about string splitting anyways ...
