That's because `str` is initialized by a literal and you can not change 
it by definition. When you call `toStringz` it duplicates that literal 
(adding terminating zero at the end) and the duplicate is mutable. I 
would recommend do not use `toStringz` and just make duplicate of the 
literal - https://run.dlang.io/is/vaosW0
