The compiler accepts this with no errors, but this is wrong code:

enum int[1] a = [0, 1];
void main() {}

See also related bug 3949 .


Another case, this compiles with no errors, but it's bug-prone:

const real x = 1.2;
real[4][4] M2 = [[0, 0, 1, x], [0, 0, 0, 1]];
void main() {}

----------------

This doesn't compile:

const real x = 1.2;
real[2][4] M2 = [[0, 0, 1, x], [0, 0, 0, 1]];
void main() {}


But the error message is bad and can be improved:
test.d(3): Error: cannot implicitly convert expression ([0,0,0,1]) of type
int[] to real[2u]

----------------

This code:

real x = 1.2;
real[4][4] M2 = [[1, 0, 0, x],
                 [0, 1, 0, x],
                 [0, 0, 1, x],
                 [0, 0, 0, 1]];
void main() {}


Produces the following errors (I don't know if this is correct):

bug1.d(5): Error: non-constant expression x
bug1.d(5): Error: non-constant expression x
bug1.d(5): Error: non-constant expression x

Fixed DMD2.045 (same root cause as bug 3974).
Note that the final case in comment 1, the unhelpful line number is bug 3394.
The first case in comment 1 is a duplicate of bug 3849. The other cases are
fixed.
