I'm torn about the issue. I see reasons to have const by default (or even
immutable), but having it as the 'real' default would as you say, turn
away too many programmers.
Hence, I suggest that modules may be marked default-const:
const module foo;
int n; // const int
mutable int m; // int
This could also be extended to cover pure:
pure const module foo;
Is this a good idea? No idea.
I think you could still get something very related by
const {
// entire module here
}
That of course, doesn't affect locals.
