A-hem, it sounds more like a job for Boost.Proto, which is specifically
designed for transforming C++ expressions both at compile time and runtime.

The op said:

If foo and other are proto expressions (which be easy to engineer), this
expression will generate a proto expression tree that you can pass to a
proto transform to do anything you want.
