This is exactly what Jonathan suggested in the post above. And yes,
it's how string is handled:
alias string = immutable(char)[];
This so far appears to do what I want. The only problem is that it
introduces an extraneous symbol, which I would prefer to avoid.
What problem do you want to avoid? This is a common D idiom. Alias
names are very short-lived. Yes, it's another symbol in the namespace,
but it will never make it to the object file. It won't even make it to
error messages -- you'll see Msg_ there instead.
Yes, I saw his answer after I'd posted my resolution.
It works, it's just not the syntax that I'd prefer. And it leaves me
wondering exactly what
immutable class Msg {...}
was declaring.
