I was surprised to read from the FreeBSD documentation that D string literals are actually writeable in Windows:

https://dlang.org/dmd-freebsd.html

Can we fix that? I think C literals were already immutable, though I'm not sure about the particulars of the Visual Studio C/C++ semantics.

I don't think that is true anymore, but even if it is, you would have to cast away the language-level immutable to get to it, so it is undefined behavior anyway.

They're not writable in the sense you think so it doesn't really matter.

Strings are still constructed as immutable(char)[] on Windows. It's the same across all platforms.

I guess the difference is that you can cast immutable away and that's UB and thus it doesn't really matter.

I know in the D1 days when a string literal was of the type "char[]". Then string literals were placed in a read only section in the binary on Posix, trying to modify a string literal caused a segfault (or similar). On Windows it worked fine to modify a string literal.

Please provide an example of valid D program that does this.

Seriously though, it would be a nice thing to have.
