Proposal on CDL - Issue CET-03

Issue CET-03. Should you be able to resume a choreography where the 
exception occurred if the exception block managed, for example, to fix 
the problem.




I propose to close this issue for the following reasons.
Nice in theory but not practicable. It would be akin to having a try 
catch block in Java for every statement and putting the block into a 
single method so that it could be recalled. The normal way of using 
exception suggests grouping expressions into a block and then calling 
that block again from within the exception should it be needed.

Not sure if I am correct but I think you can call a perform from inside 
an exception block. If so then all of the expressible power needed is 
already provided. If not then perhaps we need to consider allowing a 
perform to be called from inside an exception block.

Cheers
