--- Comment #1 from ag0aep6g at gmail.com ---
You're calling `front` without checking `empty`. The range documentation [1]
says: "Calling r.front is allowed only if calling r.empty has, or would have,
returned false." There's no mention of range implementations having to throw an
exception in such a case, so `filter`'s behavior isn't wrong.

I'm closing this as invalid. If you'd like `filter` to throw an exception here,
please file a new issue with severity set to "enhancement".
