Bug 3948 – Array literal assign to array of different length

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.
