Tooling issues should already have been solved for lambda, but if you don't like the colon, go with one of the other options - Brett expressed support for 'then', which makes very good sense (it does require creating a new keyword, but it's a fairly safe one).

Just to note, if a token is desired, it could be treated as a pseudo-keyword much like 'as' was prior to 2.6 (or 2.5 with future 'with_statement'). That is, it is only treated as a keyword when parsing the expression defining its use.

With that, the list of available "keywords" becomes much broader.
