I see that there is a difference in what either of us means by an
"anonymous function".

I mean something like the body of a def method without a name - what
you get when you use the method() function (i.e. opaque scope, no
closure) - you mean lambda (i.e. closure).

Yes, I hadn't thought of the cost of setting up a new scope (silly
considering that is one of the main reasons I would like to see
anonymous functions). I guess the only real way to find out would be
to try it.

Shame - I thought the lambda/def distinction was a good one.

Ah well. Different eyes I guess :)
