Hi all,
Seems like this topic was previously raised, but what if we add possibility to
decorate non function properties in class:
```python
class Neuron:
@linear_activation
activation
```

What would that decoration do, exactly?
In one of my projects I'm reusing class-level type annotations to identify
relevant attributes for serialization, e.g. similar to the following:
attrs = {name: getattr(obj, name) for name in get_type_hints(type(obj))}
This is convenient because it merges the type annotations from the various
The primary issue I was trying to find a way to reliably and clearly avoid
conflicts between the index labels and the positional argument names. So
if you have:
__getitem__(self, index, **kwargs)
You can't have an index label named "index", because it conflicts with the
"index" positional argume
The following comment is from the thread about adding kwd arg support to
the square bracket operator (eg, `Vec = Dict[i=float, j=float]`).

Thank you all for your posts. I'm busy now and for the next few days, so
have little time to respond. Here's some comments and suggestions.
I hope that Andras, Caleb, Stefano, Neil, Joao Bueno, Todd and Stephan will
take a special interest in this post. In the previous thread, these people

This definitely feels to me like though if an oddball case that "write your
own function" seems like the best solution. I accept the OP needs it, but I
have trouble imagining that many others would.

Maybe get-type-hints can be refactored to make writing such a function
simpler. IIRC the part that takes a single annotation and evaluates it is a
private function.

I forgot that there's also Ray:
https://github.com/ray-project/ray
Ray uses Apache Arrow (and Plasma) under the hood. It seems Plasma was
originally developed by Ray team.
Don't know how they solve the GC problem. Maybe they disable it.
