RE: [wsbpel] Issue 36 - Multiple instances of event handler

[Francisco Curbera <curbera@us.ibm.com>]

If I understand it right, we're essentially agreeing on the concept, and
ready to argue about syntax - at least regarding how to treat the message
variable. I understand the concern about introducing new constructs in the
language. On the other hand, a simple, recognizable syntax is important for
developers. Implementers would care more about having clear operational
semantics than about the details of the syntax, I think.

I think you guys are trying to hard to map this into functional programming
style. In the pass-by-value world, a functional argument merely exposes a
variable declared inside the function scope to the calling scope (so it can
be initialized by the caller); typing the argument in the function
decleration is a notiational convenience for the programmer so that he does
not have to declare the variables twice (ala old K&R style C declerations).
