Having seen all kinds of abuse of C macros or python metaprogramming I can't even imagine the mess this could create. Some people just seem to love the idea of creating a undebuggable Frankenstein macro system just so they can save 3 characters of code when writing foo.bar instead of foo["bar"]. Python libraries depending on @ annotations everywhere is another favourite. You save 1 measly line of code by not having to call or register the function somewhere but you loose so much more as you can't control initialization order and your program usually is forced to store it's data as global state. I do see the powers and benefits this can give but with great power comes great responsibility. It must be truly isolated to places where you absolutely need it instead of just for fun.
