I=E2=80=99m undecided on this. However, `using` might be easier to understan=
d since `use` could be confused with the existing keyword.

In general, I support this RFC. I=E2=80=99d like to see examples from other p=
rogramming languages, though. You mention C# and Hack above. Can you elabora=
te in the RFC on how they implement this functionality? What about other pro=
gramming languages? I know some (Rust maybe?) are scoped to blocks by defaul=
t.

Cheers,
Ben
