Posted in reply to Nick Sabalausky | http://d.puremagic.com/issues/show_bug.cgi?id=9359 --- Comment #4 from Nick Sabalausky <cbkbbejeap@mailinator.com> 2013-01-21 16:17:43 PST --- They can be concatenated with arrays, thus producing another array. But thinking about it more, defining 'int~int' to result in 'int[]' would be inconsistent with the fact that 'int[]~int[]' results in 'int[]' instead of 'int[][]'. This does result in some annoying inconsistencies: int[] a = [1] ~ 1 ~ 1; // OK int[] a = 1 ~ [1] ~ 1; // OK int[] a = 1 ~ 1 ~ [1]; // Fail int[] a = [1] ~ [1]; // OK int[] a = 1 ~ [1]; // OK int[] a = [1] ~ 1; // OK int[] a = 1 ~ 1; // Fail But I guess I don't see a way around that without introducing the more error-prone inconsistency of: [[1]] ~ [[1]] --> int[][] [1] ~ [1] --> int[] 1 ~ 1 --> int[] -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
