recur in clojure is also easy to read in my opinion.

True.

However, a named let in Scheme is not a loop. Its still a lambda.

Which means you can have nested lets with TCE, and you can construct them on the fly, depending on what your needs are, usung patterns like currying.

That flexibility just doesn't work on the JVM. You can force it, but it'll be slow and horrible compared to another pattern - and I don't think a LISP should tell me how to do something. That's Python's ideology.

It pops up every now and then in Java Language Summit presentations, usually in comparison with .NET, which does support it.

So who knows, maybe some day the JVM finally gets it.

Well the .NET CLR was designed by a lisper.
