Using shared function from different blocks II

I've decided to use simple way to share a function which presumes that block B uses parameter space P. This can be implemented in the easiest way just by sharing value p. In this scheme block A uses a known parameter space P, so does block B. Block B includes some class which incapsulates calculation with known algorythm which uses parameter p received from block A.

This way is much less interesting and not so "fuzzy", cause it uses some predefined algorythm for creating value p in block A and predefined algorythm of using this value.

But a task with serializing function with dependencies from outer scope is still interesting problem to solve.
