Sure. I think that one-dimensional numerical definite integration is a
sufficiently simple concept and the algorithms are sufficiently mature to
warrant some easy to use standard interface to be included in boost.

This is completely different for multi-dimensional integration (maybe
except you restrict it to Cartesian regions in, say, no more than four
dimensions) and ODE solvers.

The consequence is, that the design of an "integration interface" for
boost should be restricted to one-dimensional integration.
