I stumbled across Pair by accident and didn't find anything in the way of
docs, so I started playing with it and looking at the source.
I can't figure out what the use case might be. It doesn't appear to be
type-optimized; that is, it doesn't use type parameterization to provide
speed/efficiency gains. It appears to allow Any=>Any, which I guess might
be useful, but I don't see how it might be better than a tuple. Using it in
lieu of an explicit type such as
immutable Edge
src::Int
dst::Int
end
results in (my) code being an order of magnitude slower - I assume it's
because I've specified the types of the members.
What is the intended use case for the Pair type, and did I miss the
documentation?
