and pass-by-alias
Speaking of alias, one killer feature would be to enable using alias
for expressions. E.g.:
struct Window { struct Point { int x, y; } Point point; }
void test() {
Window window;
alias window.point.x x;
// use 'x' here which is really window.point.x
}
It makes it simpler to manipulate nested structs and their fields by
reference without involving pointers or using with statements. AFAIK
C++ can use references for this purpose (ala&int x =
window.point.x;), but I guess this isn't very efficient unless the
compiler can optimize it.
Besides myself I've also seen other people request it (I think Nick S.
wanted the feature).
I want this feature as well. I also want it to be possible to document.
