  Personally, I find that a little bit cryptic.  I prefer to name
things using variables or functions, and use maybe more verbose
expressions to define them.

  AMHA this kind of short-cuts are useful when either they are used
enough time to be an idiom, or to write an expression to be used once
and then thrown away.
