Fixing lambda
In a recent thread on python-ideas, Nick Coghlan said:
The reason I keep beating my head against this particular wall (cf. PEP 403's @in clauses and PEP 3150's given suites) is that my personal goal for Python is that it should be a tool that lets people express what they are thinking clearly and relatively concisely. As far as I have been able to tell, the persistent requests for "multi-line lambdas", cleaner lambda syntax, etc, are because Python doesn't currently make it easy to express a lot of operations that involve higher order manipulation of "one shot" callables - closures or custom functions where you *don't* want to re-use them, but Python still forces you to pull them out and name them.
