I'm using Arnaud Delobelle's technique (see below) to insure that only
the appropriate methods are called. A great, practical example of a
decorator.
<snip>
functions = {}
def register(func):
functions[func.__name__] = func
return func
@register
def foo(): print "Foo!"
@register
def bar(): print "Bar!"
>>> functions
{'foo': <function foo at 0x6f2f0>, 'bar': <function bar at 0x6f330>}
>>> functions['bar']()
Bar!
</snip>
Thanks for your feedback,
Malcolm
