Separate API and Implementation?

Hmmm - I just noticed that this doesn't make sense.
The separation between API and implementation should be
orthogonal to modularization, for instance to allow that
modules provide their own API.

IIUC Cocoon's "real blocks" should even support
polymorphism
at block level, which means that multiple blocks can
implement
a specific interface.
