[rules-users] Calling a function from When part

[Wolfgang Laun]

It isn't reasonable to expect readers to understand
incomplete code. There is no way we can know where
the list comes from, where and how it is stored and
passed to the function.

But one thing is sure: There is no way you can interleave
the execution of right hand sides the way you expect it.
Once a RHS executes, it is a "run to completion", (except
when an exception is thrown.)

Rather than posting incomprehensible pseudo-codes,
state *what* you need to do, not some way how (not)
to do it.
