As you suggest, more accurately, you'll require the next person who debugs your code to read this, making them much better at debugging your code.

I no longer use magic and completely avoid meta programming in python. It confuses everyone, is not needed (just use a boring factory function), and severely limits who can help you work on your code, for what? A few lines of less boilerplate here and there? "Succinctness"? Some sort of "elegance"? More likely, a DSL that nobody understands but you!

The more I write, and mostly the more I interact with other people, the more I realize that code needs to be boring. No magic. I think this is why go is succeeding: no magic.
