I have no knowledge of Lua, but I don't see what is problem with print
here, the function print is supposed to print output to output device
in most of programming languages, just as in this case, so I don't
understand why we should want to use return (which is supposed to
return some data / pointer back to function it was called from) in
this case? I mean if we can pick if we should use print or return as
recommended way to print text, I would vote for print(), especially if
it has better performance that the implementation using return.
output buffer has to be "catched", while return value may be more
complex than just a text, being processed via API or another way. Not
all of the scripts should generate plain text. My extension will need
nested arrays (or simple objects) to process, some of another extensions
probably too.
