D'oh, sorry, that should have been illegal syntax, e.g.,

     (x*y for x,y in *) ? # "*" as mnemonic for call *args
so
     (x*y for x,y in *)(3,5) # => 15
or
     (x*y for x,y in *)(*[3,5]) # => 15
etc.

Hm, along that line why not

     (x*y for x,y in **) ? # "**" as mnemonic for call **kwargs
so
     (x*y for x,y in **)(x=3, y=5) # => 15
or maybe even
     (x*y+z for (x,y),z in *,**)(3, 5, z=200) # => 215

Though I see this is moot, since Guido decided to "keep lambda,"
(+1 on that, although this is kind of growing on me, no doubt from
partial ih-factor ;-)
