The C/Lua 5.0/Lua 5.1 way looks a lot more readable to me, compared to
the C++/proposal method.
The reason being, with the format string, in a glance I can see what
the output will look like. With the stream, I have to put all the pieces
together in my mind first.

Well, at this time, the feedbacks seem clear : everybody is happy with minilanguages.As seasoned C developer, I know (and I daily use) the `sprintf` formating, so I am biased.But the pack/unpack minilanguage is not obviously readable.And same thing with `os.date` which uses the C `strftime` minilanguage.An implementation based on a minilanguage doesn't allow user extension, for example, you cannot add a "%Q" option to `string.format` in pure Lua.François
