Clearly I messed up the branch and now there are tons of duplicate commits. If there is a decision to accept this I'll create a new pull request with everything...

For each sub command it doesn't seem to be possible out of the box. One injector per macro is not a problem since the injector is injected inside the macro,...

It returns `true` if a type is mapped to something... meaning that `injector.getInstance()` will return a value and not throw an exception. It doesn't really matter if it is value...

I think erasing the values makes more sense because you want the injector to update everything in the command and since injector doesn't have values it will inject no value....
