No. See "fixpoint combinator."
But that's a somewhat flippant response. More to the point: if you
want recursion, one way or another, you need to be able to refer to
the function in question. 'arguments.callee' allows you to refer to
it but violates the Tennent Correspondence. So, given that you can
either refer to the function this way:
var foo = bar() { ... bar ...}
or this way:
function bar() { ... arguments.callee ... }
... it's not clear to me what advantage the latter has over the former
(IE bugs aside, that is). Anonymity itself doesn't seem to be a
virtue.
