I took a brief look at this. As far as I could tell Atry's library is
stateless. So, it can only support a subset of the expressions that
Boost.Lambda supports... namely those without state; i.e. all the
parameters need to be unbound. So, it can do

_1 << _2 << _3

... but not ...

cout << _1 << endl

I'm not sure that this wins you a time savings over Boost.Lambda, but
I believe it could win you a space saving if the static function can
be inlined. I wonder how this relates to the anticipated rewrite of
lambda using Phoenix.
