Your feature request related to a problem? Please describe.

I've run into runtime bugs when adding a new field to a "service-like" struct (a FooService or something like that), but then I find out someone's instantiating the struct without a constructor so some code somewhere breaks at runtime because of a nil pointer!

Describe the solution you'd like.

I'd love to see two linters created:

• structs that should have a ctor, which don't have a ctor
• structs that do have a ctor, but which are instantiated without using the ctor

These linters would definitely want to take regexes that specify the types of structs that we consider to be lintable -- most structs don't have this problem since they're just data and we really don't even want a ctor for them.

Describe alternatives you've considered.

Pray our tests catch this stuff! 🙏

Additional context.

I've written these linters already (and they're useful for me), but I didn't want to create a PR without gauging interest first.

I'm new to this project, so thanks for your patience!
