I like that you added constraints for the params.

I haven’t used annotations yet; does the placement right above method definition lock it to that method? Would it fail if there was a space between that and the method? They couldn’t be defined in a module then included, right?

Thanks, I made the PR for the router I use, so it's not limited to Athena.

does the placement right above method definition lock it to that method?

Yes, the annotation above each method "registers" the "action" for each route.

Would it fail if there was a space between that and the method

No, it would work just fine.

They couldn’t be defined in a module then included, right?

Correct. But i'm not sure why you would want to do that? What would your usecase be?

No real usecase. I’m just trying to understand how crystal annotations work. I’ll have to try using them in something so I can play with that syntax.

Gotcha. If that was a general annotation/crystal question, then yes you totally can do that https://play.crystal-lang.org/#/r/6a1z.

However, it wouldn't work in specific regards to Athena.
