It seems unnatural to use such a name when the variable has

do with pointers - it doesn't contribute to the readability.
Yes, it's
trivial, but small things cumulatively matter. Adam tends to
use int
and when that gets mixed up with an auto size_t (eg via
length) then his
code doesn't compile on 64 bit. And if it happens with his
code, you
can imagine this isn't a problem that inexperienced users
never encounter.
ptrdiff_t is in the C spec, ssize_t is not. No reason to name
all the types of snow here.
A machine-word-sized signed integer is ptrdiff_t.

Whatever - it's not that important to me. D isn't C, and has
learnt from C's mistakes and infelicities. I love the beauty of
C, but I'm glad I don't need to do my work in it. One reason why
D is under appreciated is that these seemingly small differences
make a big difference in practice, even if in theory they
shouldn't. Initially I was quite offended by no loop aliasing.
Until I saw how much time it saved me in avoiding silly mistakes.
But really there are better things to worry about at the moment.
