1623	fusion needs a reverse_fold algorithm	Eric Niebler	Christopher Schmidt	"I can fold a reverse_view, but that's a little awkward, and TMP-heavy. That is, it instantiates more templates than are needed. Would be nice if Fusion had a reverse_fold algorithm, like MPL.

This is needed for Proto, which has a reverse_fold transform based in part on fusion::fold and reverse_view. I've had to introduce ugly PP metaprogramming to avoid calling fusion::fold because of the long compile times."	Feature Requests	closed	Boost 1.44.0	fusion	Boost Development Trunk	Optimization	fixed
