--- Comment #1 from bearophile_hugs@eml.cc ---
A possible solution is to replace this:


auto enumerate(Enumerator = size_t, Range)(Range range, Enumerator start = 0)
    if (isIntegral!Enumerator && isInputRange!Range)
...
        if (overflow || result > Enumerator.max)
            throw new RangeError("overflow in `start + range.length`");
    }
}
...



With this:


auto enumerate(Enumerator = size_t, Range)(Range range, Enumerator start = 0)
@nogc
    if (isIntegral!Enumerator && isInputRange!Range)
...
        if (overflow || result > Enumerator.max) {
            static immutable err = new RangeError("overflow in `start +
range.length`");
            throw err;
        }
    }
}
...


But I don't know if immutable errors are really correct.
