Yep, just checked in the debugger. So, that's actually a bad thing, then. Good thing its being deprecated!

A weird thing happened: I was building a dictionary struct which contains a custom array of values and a differently-typed custom array of keys. Both of them implicitly define "clear" by aliasing a backing array. The dictionary type doesn't have clear, though. And it doesn't alias anything.

Just for clarification, I wanted 'myrange.at(i)' to be the same as `myrange.dropExactly(i).front` (so I don't assume it's a random access range). >> myrange.dropExactly(i).front makes it much more obvious what you're doing and that it's inefficient. It might be necessary in some cases, but we don'
