Is it not possible to alias a mixin to just one letter, and
then use it to have any syntax we want... something like this:
x("@attribute(Serializable.yes) int a");
Sure, but there's still the issue of using attributes for
codegen. For instance compare:
struct Test {
@GC.NoScan int value;
}
to, the current:
struct Test {
int value;
this() { GC.setAttr(&value, NO_SCAN); }
}
How can we do that with mixin templates? If attributes where a
language type the compiler could exploit in a consistent way, It
would be *trivial* describing this behavior in a declarative way.
