Is it only the "*add* two things" or are you decrying any generic
operator that gets evaluated and then drops the result?

Steven recently opened a thread ["Bash-like pipes in Python"] where
this exact sort of thing would be done:

  get_values() | filter("smith") | sort("income") | send_to_printer()

Several different solutions were posited with varying degrees of
conciseness-vs-pythonicity-vs-pipe'ness.

That said, I'm in the "let the compiler accept valid syntax; leave it
to the linter" camp.
