The bind headers are large, but self-contained. Other boost libraries have
smaller "main" headers but relatively many dependencies, so the end result
is about the same, if not larger.

The size of the library is mainly due to the support of up to nine
arguments. The maximum number of arguments is not enshrined in the
specification; it's supposed to be an implementation quantity (as in annex
B.) The reference implementation supports so many arguments for two reasons:

* it's much easier to scale down a 9-arg version than to scale up a 2-arg
* a proof of concept is needed that implementation difficulty scales
linearly with the number of arguments.
