Heh. I just made an issue for exactly that purpose.

What about tests? It seems difficult to test something like this
without
some test classes that actually use type annotations somewhere.
Right now my idea is to put Java 8 specific tests in a special
package, and
exclude that package unless a special Maven profile is activated. I
assume
something equivalent is possible with Ant.

We can't limit the build enviroment to Java 8, but we could remove

That actually brings up a pain point for doing this in Guice: adding
ElementType.TYPE_USE to the targets for @Named would make Java 8
required
to build Guice. Not sure how feasible that is for Google.
JSR 330's @Named doesn't have that problem because it doesn't limit
@Named's targets at all.

I'd be open to any of the following:
a) Hard-error on a qualifer/bindingannotation on types
b) Support qualifer/bindingannotation on types, but fail if it
also
exists on the variable
Though, since this'd be a change to the way jsr330 things are
interpreted, seems like it'd be best to poll the jsr330 folks and
make sure
all various implementations (Dagger, Spring, etc..) are on-board
with the
same solution.
The 330 spec says that "A qualifier annotation
- may have restricted usage if annotated with @Target. While this
specification covers applying qualifiers to fields and parameters
only,
some injector configurations might use qualifier annotations in
other
places (on methods or classes for example).
I was on the 330 EG. My memory is that this wording was chosen
specifically to allow for the future use of type annotations, which
were at
that point in an "any day now" state (and had been for quite some
time).
