I already guess that I've missed your point, but to prove it...
I was referring to the beginning of this thread
where George noted that
palettes = dict((w,set(w)) for w in words)
runs slower than
palettes={}
for w in words:
palettes[w]=set(w)
The reason seems obvious: the otiose tuple creation,
but there is no "more efficient" syntax to use with 'dict'.
