Amen.  *If* we were to introduce 'of' as an operator, at least it
should introduce some as-yet-unsupported parameter passing semantics,
like call-by-name. :-)

And in fact, I think that

  sum(x for x in range(10))

reads *better* than

  sum of x for x in range(10)

and certainly better than

  sum of x for x in range of 10

because when you squint, it just becomes a series of undistinguished
words, like

  xxx xx x xxx x xx xxxxx xx xx
