It's annoying to fix all these `int index =
str.indexOf("something")` to size_t/ptrdiff_t because you
started writing the code thinking that indexOf returns an
integer even though it returns a ptrdiff_t. When porting code
from 32bit to 64bit you need to fix all these lines which can
quickly become quite complex from functions where you don't
expect them to return size_t or ptrdiff_t
Adding a warning when trying to do something like `int i =
funcReturningPtrdiff();` would make porting easier because you
would already spot the issues on the OS/architecture you are
working on. This also affects porting windows to linux as DMD
on windows uses 32bit by default and on linux it uses the
architecture you downloaded as default.
There already was a such bugreport.
size_t is simple alias to int/long depending on the platform.
So currently it's impossible without adding a new type in the
frontend.
