What if it were package instead of private?
This wouldn't help, sum is in phobos, Duration in druntime.
The answer is that sum shouldn't be too clever. IMO, initializing to 0
should be only done if the type's .init value doesn't match 0. Since
only floating points and char/wchar/dchar do this, just do the Seed(0)
for those, else use Seed.init.
I take the last part back a bit. Some custom types may default to
NaN-like values, so Seed(0) is necessary.
What should happen is that sum should test if Seed(0) is viable, and if
not, use Seed.init.
