The idea sounds very cool, of course. However, at the moment I don't
fully understand where the *code size* (vs, application memory
footprint) reduction comes from, at least not from a quick glance to our
locale from that point of view... Are you willing to explain in little
more detail?

Likewise ;)

Paolo.

P.S. Why in computer science "lazyness" is always a virtue and is never
in real life? ;)
