How about this?

function split(s,t)
 local a={}
 gsub(s,"(.-)"..t,function (x) tinsert(%a,x) end)
end

(This assumes that the separator t occurs at the end of the string s too.)

gsub only creates the the strings for the captures and the string that is
returned (in this cases, the returned string is ignored).
