I used to have the following code to collect all (old style) class
names defined in the current module to a list called reg:
def meta( reg ):
def _meta( name, bases, dictionary ):
reg.append( name )
return _meta
reg = [ ]
__metaclass__ = meta( reg )
class c1:
pass
class c2:
pass
print reg
This would correctly print [ 'c1', 'c2' ]. Now I would like to switch
to new style classes but replacing class c1: and class c2: by class
c1(object): and class c2(object): doesn't work because the metaclass
associated with object will be called and not mine. Of course if I
would add __metaclass__ = meta(reg) to all class definitions that
would work, but how do I do this on the module level?
