--- Comment #3 from Paul Backus <snarwin+bugzilla at gmail.com> ---
This is a special case of a general problem with ranges and const. A const
object cannot implement popFront (which mutates its receiver), and therefore
cannot be a range.

In this case, the problem can be worked around by using the [] operator to
obtain a mutable slice over the const array:

---
const x = [1, 2];
auto y = choice(x[]);
---
