And has an 8-bit size_t?
Just found the bit I read before and was trying to find again
"Use size_t as an alias for an unsigned integral type that can span the address space.
Array indices should be of type size_t."
Of course, anything below 32-bit is irrelevant to D, but according to cplusplus.com size_t
is defined to be the type returned by sizeof. But where it explains sizeof it doesn't
state what type that is, and I don't know what the C or C++ standard says about it.
