immutable static int[] data = [1]; static this() { data.length++; } void main() {} DMD 2.066alpha gives an error message that is both wrong in contents and refers to the wrong line: test2.d(1,31): Error: constant 1u is not an lvalue Expected is an error message like: test2.d(3,5): Error: cannot modify immutable expression data
