[Python-ideas] Simpler Customization of Class Creation - PEP 487

[Sven R. Kunze]

Nice. I am glad to see movement and practical usage in that area.

Metaclasses have been a headache for a long time. We introduced them 
into our production for a short period of time just to remove them later.
As the PEP expected, ABCMeta was the issue. We will see if the proposal 
will solve that.
