It's probably worth hanging onto the id, in case the same function (from the same line of code) is used in multiple contexts. But IMO having the text of the function would be very useful - as long as it can be done without costing too much time or memory. So I'm +0.75 on the idea, with the caveat that it'd have to be implemented and performance-tested to make sure it doesn't kill the common case of a lambda function being created, used, and then dropped (think of a sort key function, for instance).
