Very informative!

Have you considered adding randomized tests to Phobos? For instance, for the sum() example, you could generate a random array x, say, 100 times and assert:

sum(x) == x[0] + sum(x[1..$]);

which is pretty much the defining property of the summation function (along with sum(a)==a[0] for an array of length 1).
