Yep.

I deliberately designed the expression.hpp interface so that LL is a
(nearly) conforming implementation of it.

The only differences are (1) the names - they would hopefully be
standardized during the formal review process, whenever this happens, and
(2) the fact that LL::bind() allows a "free" first argument, whereas I
intentionally defined two separate functions, apply and call.

What surprises me, however, is that while it's clear to me that ETs are a
"good thing" (tm), it seems that nobody cares to use them. :)

Is MSVC compatibility so important? (I tried. I really tried.)
