1082 – The .offsetof property yields a signed int, a size_t would be more appropriate

The .offsetof property yields a signed int value, an unsigned int like size_t would be more appropriate. Also the exact type yielded by .offsetof should be documented in the Portability Guide of the documentation. The types yielded by .length, .sizeof, and .alignof are specified there. 
/*
	dmd -w -O test.d
	./test
	size_t type = uint
	sizeof type = uint
	alignof type = uint
	offsetof type = int
*/
import std.stdio;
struct foo {
	int bar;
}
void main() {
	writefln("size_t type = ", typeid(size_t));
	writefln("sizeof type = ", typeid(typeof(foo.bar.sizeof)));
	writefln("alignof type = ", typeid(typeof(foo.bar.alignof)));
	writefln("offsetof type = ", typeid(typeof(foo.bar.offsetof)));
}
