I tested this code: import std.stdio; void main(){ double[] a=[1,2]; double[10] c; c[]=a[]+0.; writeln(c); double[] b=[1,2,3,4,5,6,7,8,9,10]; double[10] d; double[] e=b[0..2]; d[]=e[]+0.; writeln(e); writeln(d); d[]=e[]; } with the following result: [1, 2, 0, 1.28823e-231, 1.11255e-308, -1.43745e+306, 0, 1.28823e-231, 1.56648e-307, 0] [1, 2] [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] object.Exception src\rt\arraycat.d(31): lengths don't match for array copy ---------------- 415330 4151BB 406DC4 406DFE 406A1F 41C425 ---------------- Unless I have missed something, it seems that: = tests the length of the array and implies an exception BUT: + does not test the length, and it is thus possible to read information which are not allowed... For information, I was testing how []+ were handling smaller array (e.g. Error? completed with nan? completed with 0.? cyclic computation?)
