But it is 'Helper' bound in the scope of the *definition* of __init__,
hence you *could* write:
>>> class A(object):
... def _helper(x): return '<<%s>>' % x
... def __init__(self, msg, _helper=_helper):
... print _helper(msg)
... del _helper
...
>>> A('spam')
<<spam>>
<__main__.A object at 0x70170>
Confusingly yours,
