How is a "proper tail call" implemented if you aren't talking about conversion to iteration? I found the following article helpful. http://www.drdobbs.com/jvm

  Usually it is implemented by reshuffling stack frame + jumping to the call destination. See how it is done in .NET, for example. Do not confuse tail recursion, which is the least interesting narrow case of a tail call, with tail calls in general.

    Why can't you modify a JVM to do this? I don't get it.

      Of course you can (but you have to add another instruction or an instruction prefix). But Oracle won't ever do it.
