Which is why I didn't like the 'sum[x for x in S]' notation much.
Let's look for an in-line generator notation instead.  I like

  sum((yield x for x in S))

but perhaps we can make this work:

  sum(x for x in S)

(Somebody posted a whole bunch of alternatives that were mostly
picking random delimiters; it didn't look like the right approach.)
