Is there an easy way for a class to incorporate an existing module but  
also stipulate that it will capture any value returned by the methods  
in that module into one ivar?

Sorry Gilles I have no Ruby and an impossible keyboard at hand, but  
the basic idea would be

module M …  
def self.included into\_mod  
methodes.each do ! mn !  
m = method mn  
into\_mod.send( :module\_eval, “def #{mn} \*args, &blk;  
@{mn}=super(\*args,&blk);end” )  
etc.etc.
