I like this one. However, it actually should be:

format(" $1 $2 $3", make_tuple(x, y, z));

and this is already less attractive, at least for me. Still, I think it's a
move in the right direction :).

My main problem with '%' is that it's not an idiomatic C++, at least not yet
:). Also, using of '$' in format specification, but '%' when providing
arguments seems inconsistent.
