As it stands, Guido van Rossum has suggested that lambda forms will disappear in ["Python3.0"]. This started a number of threads on comp.lang.python suggesting alternate syntaxes for lambda in the hopes that one of them might be more amenable to GvR's tastes. This pages summarizes these suggestions:
Current Syntax
New Syntaxes
Args Before Expression
Nick Coghlan: def-to syntax #a 1
Nick Coghlan: def-arrow syntax #a 1
Alex Martelli: def-as syntax #b 2
Dave Benjamin: fun syntax #g 7
Roman Suzi: quote-colon syntax #i 9
Expression Before Args
Nick Coghlan: for syntax #f 6
Robert Brewer: for (no-parens) syntax #c 3
Nick Coghlan: def-from syntax #d 4
Michael Spencer: from-args syntax #e 5
Michael Spencer: for-args syntax #e 5
Bengt Richter: colon-function-application syntax #h 8
