I agree -- though I'm not to be trusted, as I also tend to like the
highly unpopular placing of do/end on one line....  In fact, I've gone
over almost exclusively to do/end, especially now that one can chain
them.

I originally liked doing that, especially with do/end:

  things.each do
    |t|
    puts t
  end

An argument could be made that breaking the line between the "do"
directive and the start of what it is you're "do"ing makes sense.

I've actually trained myself to put the |t| right by the "do" because
I didn't see many people using the above style.  But it does seem to
be appearing more.
