The same as there would now; since the rescue clause is not inside the 
do/end block, it is not affected by this proposal.

The difference would be that your version would also rescue exceptions 
raised by File.open, while the proposed syntax would only rescue 
exceptions raised within the block given to File.open.

But I like the devil's advocate approach, it makes the proposals sharper :)
