Yes, it's a good idea; and that's how i started; i just can't remember all the different names.
Lazy init is a good idea too... But it adds a level to the class
It seems i am the lazy one:

def __init__(self,*args,**kwargs):
  read_and_dispatch( args, kwargs, (self.init1,self.init2, ... ) )

was what i had in mind, but unless each init has a different signature,
it's gonna get more hairy:

class Signature:
  def __init__( self, siglist ):

class TypeSignature:

class InstanceSignature:
