I don't think these were on many compilers when Jakubik wrote his library.

Still in development. There is some work being done to port to other
compilers. Also we are looking at integration to other Expression Template
libraries.

Of course!

I'm not sure I'd want this.

My guess is that he's using the binder from Lambda/BL to hold the function
pointers, extra arguments etc. I never thought about using it this way but
it looks promising. There is some more work on Lambda being done for holding
arbitrary lambda functions and this would help the callback problem. LL does
the member template stuff very well. (IMO)
