With this program:

import std.stdio;
void main() {
    uint n = 1;
    uint[n + 1] foo;
    writeln(foo);
}


DMD 2.060beta prints:

temp.d(4): Error: variable n cannot be read at compile time
temp.d(4): Error: Integer constant expression expected instead of n + 1u
temp.d(5): Error: template std.stdio.writeln does not match any function
template declaration
...\dmd2\src\phobos\std\stdio.d(1578): Error: template std.stdio.writeln(T...)
cannot deduce template function from argument types !()(_error_)

That I think is now acceptable.


Probably the errors of the second program too are improved:

import std.stdio: writeln;
void main() {
    immutable int[] A = [1];
    int[A.length] B;
    writeln(A);
    writeln(B);
}


but I can't verify the error messages because now it compiles and runs with
output:

[1]
[0]

So I have added a dependency to Issue 8400. Until Issue 8400 is undone I can't
verify this Issue 8312 is truly fixed.
