...I understand that I can't load a class from another block. My question:
Is it possible to load classes from "Cocoon core" (whatever we will
consider as core) from within my block via "new" or are there arguments
against it?...
I think loading classes directly via new (as opposed to factories + interfaces) should be discouraged as much as possible, as it creates unnecessary coupling.
Depending on the classloading mechanisms that are implemented, selective filtering of what is allowed could be implemented easily I think [1].
Do you have examples where direct instantation via "new" is required?
