FWIW:
Signed shift seems to make little sense to me personally, since we are
just dealing with a row of bits, and if you really want to do a quick
multiplication/division, you might just as well use a * or / operator -
it is not going to hurt that much:). *However*, it's been possible in
different languages since before I had my first computer (e.g. SHL/SHR
and SAL/SAR in asm x86), so we might provide the same functionality and
create a new operator to discriminate between signed and unsigned
shifts.Just a thought. Don't kill me if that would be polluting the
language.
