[PEAK] Keyword "as" in RuleDispatch

I see that RuleDispatch ("import dispatch") is used in 
peak.binding.attributes and peak.util.Graph. What activities would be 
necessary to port this code to PEAK-Rules and therefore replace the 
RuleDispatch dependency in the main package?
I am considering making this contribution.


Regards,
Alexey
