You can add an eager pairs() function to Phobos that returns an
array of tuples.
byPairs can't be done in object.d for the dependency from
tuples that aren't yet (and perhaps never) built-in in D, and
it can't be done in Phobos because it needs access to
unspecified runtime functions.
I'm pretty sure my problem isn't my code but how I've built the
