See my reply to bearophile about that.
Yeah, just saw that :)
So basically you're suggesting to implement Integer and Word
library types using compiler intrinsics as a way to migrate to
better ML compatible semantics. This is a possible solution if it
can be proven to work.
Regarding performance and overflow checking, the example you give
is x86 specific. What about other platforms? For example ARM is
very popular nowadays in the mobile world and there are many more
smart-phones out there than there are PCs. Is the same issue
exists and if not (I suspect not, but really have no idea) should
D be geared towards current platforms or future ones?
