Try this: io.write((string.gsub("Concatenation, Catharsis, 
Popocatapetl\n", "cat", "dog")))

The extra parenthesis around a function call changes it from 
multi-return to single-return.

If you don't want to put up with the () stuff in your code, try this:

function string.mygsub(str, pat, repl) return (string.gsub(str, pat, 
repl)) end
