Given the recent pattern of syntactic constructs for expressions using
<expr> <keyword> <expr> (ternary if, listcomps, genexps), and avoiding
the use of colon in expressions, maybe it should be:
sorted(range(9), key=n % 3 def key(n))
this is analogous to
sorted(range(9), foo=n % 3 if bla(n))
It also shares the property that it reuses an existing keyword and
avoids the word "lambda", originally (I presume) an homage to Church,
now considered obscure-sounding by many.
If you want to avoid the colon then:
>>> sorted(range(9), def key(n)=n % 3)
[0, 3, 6, 1, 4, 7, 2, 5, 8]
which would be syntactic sugar for:
>>> sorted(range(9), key=lambda n: n % 3)
