No. We have several types which vary in size. In addition to
real, there's
also size_t (which should be being used in almost all D
programs, whereas real
is used in far fewer), and there's also ptrdiff_t, which is
effectively an
unsigned size_t. And of course, all of the pointer types vary
in size, as do
the c_* types from druntime when you have to interact with C
(though those
aren't part of the language - or even just treated as part of
the language as
size_t and ptrdiff_t are, since they're defined in object_.d).
So, even if
almost all of D's numeric types don't vary in size, there are
some that do.
Isn't size_t unsigned and ptrdiff_t signed?
But it is true that a large portion of our platform-specific
problems stem from
types that vary in size.
