besides, nested foreach with '_' is not working. but "__"

The point is to introduce a little breaking change in D and use
"_" as "don't care", so you can reuse it for nested scoped and
for tuple unpacking, and for other similar future purposes.

I agree that _ would be the ideal syntax, but why make a breaking
change when it is unnecessary? __ would serve just as well and it
is only one extra character. It is already reserved so it would
be reasonable to put it to good use.
