But yes, an unformatted write function would be nice. See my previous post on this thread.

July 16, 2004 DMD 0.95 bug: const struct is not const. | ||||

Posted in reply to Walter | This code fails with "non-constant expression b" on the last line in DMD 0.95. It should compile normally. struct foo { int x; } const int a = 0; const foo b = { a }; const foo c = b; It's a sticky problem, but templating can't be done without it. |

We now have a newsgroup dedicated to bug reports. I'm cross-posting to it. *web interface* http://www.digitalmars.com/drn-bin/wwwnews?digitalmars.D.bugs *usenet interface* news://news.digitalmars.com/digitalmars.D.bugs FWIW, I've confirmed your bug. -- Justin (a/k/a jcc7) http://jcc_7.tripod.com/d/ |
