Shadowing globals is definitely a bad idea. Shadowing members, it's
debatable.

So are you saying D here should give an error for the shadowing of the
module-level x?

I think he meant "shadowing locals". As I wrote in TDPL, it's a bad
idea to add a global somewhere and break a bunch of code that has
nothing to do with it.

Yes, but D allows to use it. And in few cases global variable can be
useful.
For example, we can have thread-local variable for database connection
that used almost everywhere.

I agree. What I'm saying is it's not good to make shadowing a global an error. It puts the onus in the wrong place.
