I don't know ... honestly, why can't we just make the block
parameters always block-local?  Having to make closure explicit
with share doesn't strike me as very helpful.

There's also a certain "oh, by the way, that variable mentioned
earlier is actually closed over from the enclosing scope" factor. 
Not great for comprehensibility.
