>From a language perspective, I would much prefer return values instead of side effects, even if those side effects could be converted into a return value with a special print implementation. People tend to expect print to produce a visible output in any case, which will often be violated if the output is collected and then processed further by other constructs the Lua call is wrapped in. Having both would also bring up the question what to do when both are provided- should the return value be appended to the collected printed output? I am no Lua expert, but would guess that the usual collect-in-list-and--finally-join method can avoid the performance penalty in Lua too.
