Currently `scope` is documented [1] as > references in the parameter cannot be escaped and `dup` is called for unrestricted set of types so type's postblit can assign references from the parameter to global variable thus violating `scope` storage class assumptions as there is no such restrictions for postblits. This issues is cause by druntime pull #1637 [2]. [1] https://dlang.org/spec/function.html#parameters [2] https://github.com/dlang/druntime/pull/1637
