Yeah, that appears to be what's happening. For the record, I tried it on both Linux and Windows, and only got a segfault on Linux.
Yeah, that's consistent with other strings too. (The D type system calls both immutable, but the OS is looser on Windows. at least 32 bit.)
Are there cases where this behavior is useful?
Yeah, it is cool for sentinel objects and default settings. Usually best when coupled with immutable to prevent more confusion but mutable versions sometimes make sense too.
But it is rare and if you aren't specifically looking for it knowing the details, it isn't right. And since the syntax looks so normal it trips up a LOT of people.
I think the compiler should probably start to error on it, and if you know what you're doing, maybe mark it special somehow. idk.
