I hate D's policy on integer conversions. That's why I wrote
nopromote.d which I posted somewhere in these forums, that lets
you attach `.np` (for "no promote") to a short integer
somewhere in an expression to "poison" it so that all
arithmetic is done without promotion and assignable back to the
original variable.
Ah, cool. I'll have a look.
It's *really* b0rken IMO that you cannot even use `^^=` on a
short integer! I'd file a bug, but Walter has said that he's
not going change his stance on this.
Yeah, you can't use it at all.
ubyte m;
m ^^= m; // doesn't work
So this is a serious bug, not a policy anymore.
