No the _ does not convey that meaning, however I often times name my private functions suchly.
You should indeed use defp

I also like the solution (keep forgetting about String.to_integer) however I still fail to see
how it passed all tests given that it does nothing concerning the tie breakers \o/

Random tests should be added.

Is the _ for the _weight/1 to signal private use (like in python)?
If that's the case, you can use defp instead of def to declare it explicitely.

Nice work. I learnt the sirt hand $_weight/1 from this example
Thanks!

I'm new to translating katas.
I wanted to try this one in Rust. A translation is already available but not yet approved.

What is required to make this translation live?
