Does a rule exist for warning on an unused return value?

I haven't been able to find anything when searching, thought I'd double check.

Playing a little with writing a rule, but is possible to look up a function definition from a call? That is, if I find a `CALL_EXPRESSION` to function `foo`, could i look up any annotations on `foo`?  Maybe this would have to fall under a compiler plugin instead of a ktlint rule?

isn't it goes more into direction of code quality rather then code style?

Perhaps, yeah.  I'm just looking to add it in some places and trying to see what options were available.

most probably you need to look into <#C88E12QH4|detekt> rules direction
