Type checking for dataclasses

[jsh9]

Hi, I'm wondering if there can be support for type checking dataclasses? Currently, when I put @typeguard.typechecked on top of a dataclass definition, no checking happens (unless I'm mistaken).

Thanks!

Here's what I'm doing for this case:

@svermeulen Your gist works! Want to PR this to this project? Can I PR it? It needs a license.

[svermeulen]

Feel free to PR it. I've added MIT license now

Did this get merged?

[agronholm]

No, and I'm not sure what approach I want to take with regards to checking class/instance variable assignments. I don't think I will add support in v3.0. Maybe in a later release.

That's a shame. With typeguard 2 this used to work if I am not mistaken.

[agronholm]

It never did work with typeguard 2.

Hi @agronholm - are you planning to support this in typeguard 4?

[agronholm]

Maybe in some follow-up minor release, but not the 4.0 release that is imminent.

In the case when one doesn't know what approach use to a solution like this, the best is to be flexible and give a temporary solution that works for the simpler and most fundamental case, that we know most devs would use, than to not give an alternative at all. I'm sure most of use are doing almost the same. What is the issue with the proposed solution?, why not just split the logic for class, and instances, and weirder cases?
