As we currently aren't reviewing anything (We still need a review

Anybody else?), I thought I would take the opportunity to ask for
comments on a few little template metaprogramming helpers:
https://gist.github.com/1191885
Besides a few helpers for manipulating/combining template predicates,
the above link contains three main:
StaticFilter – like std.algorithm.filter, but for type tuples using
template predicates.
PApply – like the unluckily named std.functional.curry, but for template
parameters
Compose - alias Compose!(A, B, C) Comp; // Comp!D is now A!(B!(C!D)).
I had originally whipped these up on the fly while working on some
metaprogramming-heavy code, but they have proven useful in other
projects as well. What do you think? Would some of these be worthy
additions to Phobos? Do you have similar stuff lying around in your own
code?
StaticFilter definitely should be in Phobos. StaticReduce too, but you
don't seem to have it on your list. I also often use StaticIota.
For more handy templates I feel should be in Phobos, see
