JPython 1.0b3 on jdk1.1

Nothing missing.

Also from JPython:
>>> class A:
...  def foo(self, seq):
...   if seq:
...    print seq[0]
...    self.foo(seq[1:])
...
>>> a = A()
>>> a.foo([1,2,3])
1
2
3
>>>

No problem with recursion. You've made some other error for which 
you'll kick yourself when you finally see it <wink>!
