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.

Yes, I guess side effects and resource handling can be seen as equivalent. I think struggle, however, with the example. Couldn't you just write def fn() = { doSomethingElse() someExpression } Or is someExpression used by the side effect in the try-finally?
I actually meant to say "didn't throw exceptions" rather than "pure" in the original tweet... trying too hard to save characters in my tweet. So the order is significant.
