Well, from the looks of it, handful (or among or whatever you want to call it) 
is basically a functor for canFind (just with in instead of parens). So, it's 
an algorithm that's been thrown into a struct rather than kept as a separate 
function - kind of like map or other lazy, range-based functions except that 
it's using in instead of the range API. So, I think that it fits in 
std.algorithm reasonably well, but it _is_ also a bit of an odd fit. I think 
that the problem is that you're essentially introducing a new idiom, and it 
doesn't quite fit anywhere in what we have.
