It is possible and indeed commonly done. It is a core design goal and
advantage of ranges that lengthy composition works, and is readable. There
is no fundamental undocumented constraint of which I am aware than those I
have documented.

Your example works perfectly if you replace the pheonix bind operations with
functors. Hence this appears to be a compatibility issue between the
transform iterator and pheonix bind.

I will investigate further and report back, but I wanted to let respond with
what I know now in case this helps.

It is likely that you are doing nothing wrong. I would like all of the Boost
libraries to integrate perfectly with Boost.Range and your use-case looks
perfectly sensible.
