Did you know that there already is a string:rep() method?
Also, if you're doing this sort of thing a lot, you should take a look
at table:concat(). Concatenating strings like you're doing here is
extremely slow. This kind of code is considerably faster:
local out = {}
for i = 1, n do out[i] = self end
return table.concat(out, " ")
