Does someone have an idea of why it happens ? The version of parse that
is used here is :
---
std.conv.parse(Target, Source)(ref Source s, uint radix) if
(isSomeChar!(ElementType!Source) && isIntegral!Target && !is(Target ==
enum))

And I can't see which template constraint is not respected when I call
it with a slice.
It's the `ref` part. A slice expression cannot be passed in a ref
parameter. You can use std.conv.to instead or assign the slice to a
variable first.
