If it comes down to explicit vs implicit, I would prefer to see an 
explicit declaration. That way I can decide whether the partner link, 
correlation set or variable is localized to the event handler or used 
from the parent scope, in the case of correlation set actually declare 
the properties being used, and if needed, declare any other partner 
link, correlation set or variable for use specifically within that event 
handler.

If event handlers were an extension of scope, they could allow for these 
explicit declaration, and since the scope is created at the time the 
event handler is triggered, also perform local assignments correctly. 
This solution would work consistently for both partner link, variable 
and correlation set and would be easy to understand based on the 
existing set of rules.
