Since this would be a singleton, skip it and just make a module 
'registry'__ that you import everywhere

Include the following function:

def _debug():
   r = ['<pre>']
   d = {k:v for k,v in globals().items() if not k.startswith('_')}
   r += repr(d)
   r += '</pre>'
   return ' '.join(r)

Then

a = 3
b = 'ab'
print(_debug())

prints

<pre> { ' a ' :   3 ,   ' b ' :   ' a b ' } < / p r e >

 From outside the module, registry._debug() will produce the string.
