I think using "finally" this way would be more confusing
than the status quo. Currently, if you see a "finally"
somewhere, it means the block following is always executed
come what may. But with this change, you would need to
look up some arbitrary distance to see whether it belonged
to a "try" or a "for".

It's not so bad with "else" because you need to look back
to find out what condition the "else" refers to anyway.
