I took a look at the source code for `zip()`, and the cause of 
this deficiency is that `Zip` takes a `StoppingPolicy` as a 
runtime parameter, rather than a compile-time parameter as it 
should.

`empty()` and `popFront()` can both throw - but only if 
`StoppingPolicy.requireSameLength` is selected. The default is 
`StoppingPolicy.shortest`.

This design dates back to 2009, which is probably before 
`nothrow` was implemented, and certainly before `@nogc`.
