The cast(signed), cast(unsigned) feature proposal

[Mrzlga]

Andrei, what do you think about the unsigned(x) not showing up on 
greps for 'cast'? No problem? Is the grep irrelevant? Not all 
casts should be marked as a cast?

People told me the grepping was important, so I tried to work 
their idea in.


I understand, you can still search for:
"signed("                     // signed or unsigned
"cast(u"                      // unsigned
"cast( ... every type ... )"  // trying to find signed conversions


But I was trying to make the thing more predictable altogether.
