Description
I suggest adding a linter that will warn for any discarded value, regardless of its type. This would both catch unused effectful code that's not concrete IO - it would need to be disabled for blocks of side-effecting code, but I see this as an extra advantage since side-effecting code would have to be explicitly marked as such.
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reviewing the repository's existing Scalafix rules and the issue's proposal, since no implementation files or tests are identified. Define how discarded values are detected and how side-effecting blocks are explicitly exempted; done means the rule warns for discarded values regardless of type and has coverage for those exceptions.
