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.
