Instead of writing, def fn() = { val result = someExpression doSomethingElse() result } I've found myself writing code like, def fn() = try someExpression finally doSomethingElse() more, even when `someExpression` is pure. I'm not entirely sure how I feel about it.

On Scala 2.13 you could use tap: import scala.util.chaining._ def fn() = someExpression.tap(_ => doSomethingElse())
And `tap` is even better because `doSomethingElse()` can actually use the result value (e.g. by logging it)!
