@aledsage I agree in principle.
In this particular case, as Java 8 has a deeper / more precise type
inference algorithm, it refuses to compile, because it cannot guarantee that
the type of the Maybe (the capture of ?) is actually compatible with both the
`key` and the `newConfigKey` call. I wonder how it could be permitted in java
7, actually :-)
I will reinstate the generics with Object as that's the only type that's
accepted unequivocally.
