scope escapes are only disallowed in @safe code.
Adding @safe: to the top of this file makes it not compile with a complaint:
Error: scope variable z assigned to non-scope b.foo
Which I think is what you expected.
As to why it happens without @safe, you may be managing your global
variable carefully and ensuring it's unset by the time foo goes away.
The compiler can't know.
Another reason to enable safe-by-default...
