We have just considered it. Implementing it is another story. Right now,
the code generator doesn't even know when it is compiling a tail call;
it just generates code for an ardinary call, and lets the optimizer
turn it into a tail call.

In any case, it won't be just the declarative debugger that breaks.
The procedural debugger's "stack" command will also break; it has to,
because having it work means having too many stack frames :-(. That means
retry may not work either.

Zoltan.
