This does exactly in the wrong direction.

We should *not* make it easier for people to write flowscript, we should 
make it easier for people to write components for their business logic 
and not pollute the flow logic with it.

In the pyramid of contracts, sitemap + flow reside in the 
"administration" concern island, while business logic components reside 
in the "logic" concern island.

If you make it easier for people to write java in flow, they will start 
blurring this contract and the whole cocoon idea falls apart.

This is the concern that Gianugo and Guido expressed and I completely 
agree with them on this.

Please, if we loose SoC cocoon will become a mess.
