Fallback for operator and other dunder methods

[Dom Grigonis]

The issue was more of a wrapping around numpy array. Found the solution already. Unfortunately, there is no equivalent to __getattr__, the only way is to dynamically define them from meta. It seems it’s pretty standard to just have a collection of special method names and using them for similar cases. Well, at least it’s what I got to. __getattr__ feels very hacky for such case, so maybe it’s for the best.
