I'm pretty sure it's assert() here. The contract is that the 
caller is responsible for checking emptiness beforehand, and the 
whole of Phobos is coded around that contract.

I think.

If it should assert() doesn't that lead to unsafer code in 
release mode?

That's the point of release mode. Omitting superfluous checks 
based on the assumption that your code is correct (e.g. 
assumption that the emptiness contract is respected).
