Really? By how much? and on what compiler? I would very much
appreciate seeing numbers.

Are you using the latest Boost.Parameter macros to enable your
functions, or are you making lots of use of the old idioms?
Extensive use of binding<>, especially, is likely to make it expensive
at compile-time.

Let's have some numbers; if they are very bad I'll be convinced (but
also highly motivated to optimize the library).
