--- Comment #2 from bearophile_h...@eml.cc 2011-04-16 12:54:38 PDT --- That fourth idea is also useful to avoid a little trap. This code looks correct, here randomCover() is used to act like the Python random.choice(), but here it keeps taking the same value: import std.stdio, std.random; void main() { // can't be const /*const*/ int[] data = [1, 2, 3, 4]; foreach (i; 0 .. 20) { int r = randomCover(data, rndGen).front; write(r, " "); } } Output: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 The same bug can't happen with code like this, because the random generator is not created inside the foreach scope: import std.stdio, std.random; void main() { // can't be const /*const*/ int[] data = [1, 2, 3, 4]; foreach (i; 0 .. 20) { int r = randomCover(data).front; // int r = choice(data); // better write(r, " "); } } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
