@solidsnack @dibblego If it turns out you do this often enough to impact your code, something is wrong with it ;)

@alexey_r @dibblego But easy things should be easy. Do you want to remove List#head next?

@solidsnack @dibblego ... Well, Scala at least doesn't have Haskell's problems with head, where you don't get a stack trace and there's ...

@alexey_r @dibblego Yes, Scala is generally quite well-behaved here, returning a 500 and logging at the ERROR level. Go with the flow.

@solidsnack @alexey_r Well-behaved would be removing List#head from the API. Aim higher.

@dibblego @alexey_r When _/0 is still in the API, what difference does List#head make? A 500 is a 500.

@solidsnack @alexey_r "A bad API exists. Let's make them all difficult to use and horrible!" This is called Ruby Reasoning and I reject it.

@dibblego @alexey_r I don't think it's about the API. I think it's about the language.
