could we have ssize_t defined in phobos somewhere so your code ends up

ptrdiff_t
It seems unnatural to use such a name when the variable has nothing to
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.
