I would recommend that your directory structure reflects your namespace
hierarchy - not the other way around. There's a small but subtle difference.

I would have like to see such metafunctions already in boost::mpl.,

Declaring your stuff inside other people's namespaces is generally a pretty
bad idea. It may not be clear to users which features really are part of
boost::mpl, and which are not. Plus you'll have one namespace #included from
two different locations - this could be very confusing.

or put it at toplevel right below my namespace ?

Put it in your own namespace :)
