I am of the same mind here. One concern of mine is that too much of the C++
standard library has sacrificed convenience for generality, with the result
that there are no simple, convenient, and _common_ idioms for many simple,
common tasks. I suggested parallel approaches so that the the odd
11-argument constructor could be accomodated using the functor approach, but
everyone else could use the pool more naturally.
