using a simple function pointer and a void * as its argument makes the
implementation in assembler easier.

boost.context is intended to be the basis of such things like coroutines
(see boost.coroutine) and fibers (see boost.fiber).
Both libs allow to use arbitrary function objects.

The function pointer is not a callback it is the function executed in
the context and the void ptr is its argument.

If you require to use boost.function you could easily create an object
containing a boost::context and your boost:function instance. The
context executes a trampoline function which will be invoked with the
pointer to this object as argument. For more details look into boost.fiber.
