yes, it's a hack,
using a declared type (type are artifact of the compiler) at runtime (in 
the VM realm) to convert a message is not very natural.

yes, it's possible to use an annotation processor for that, it's a far 
better that trying to emulate the compiler job at runtime.
Now, requiring an annotation processor make the API heavier to use.
