People who are marginally familiar with integer promotion will
not be surprised to know that the program prints "256". What is
surprising to me is that this produced neither error nor
warning.
The comparable program in C++, when compiled with gcc,
correctly warns about signed/unsigned comparison (though, to be
fair, it seems that clang doesn't).
While this particular issue can and should be addressed in the
compiler (see my other reply), in the mean time how about trying
out my `checkedint` DUB package?
It fixes the signed/unsigned mess, and many other similar
problems, such as integer overflow:

My intention is to submit it for inclusion in Phobos some time
soon.
Note that because of various flakiness with DMD, it sort of
requires LDC or GDC at the moment.
