[...snip implementation notes...]

I admit I only glossed over your implementation notes, but it looks like
this would be very similar to (or...the same as...?) a bound (e.g., via
Boost.Bind) boost::mem_fn:

http://www.boost.org/doc/libs/1_47_0/libs/bind/mem_fn.html

Is that accurate?

By the way, this is my first active participation in any open source project
