Thanks for the playground. I see what you did with defining the `a_echo`
**proc**. I read back through some of Salewski's book (specifically
<https://ssalewski.de/nimprogramming.html#_procedure_variables>). It looks like
I was mostly just overthinking it.
Do you know (unrelated) if there's an elegant way to be able to do like a
`__repr__` on the **proc**? Here's the related compiler error:
/usercode/in.nim(13, 3) Error: type mismatch
Expression: echo act
[1] act: Action
Expected one of (first mismatch at [position]):
[1] proc echo(x: varargs[typed, `$`])
Run
