https://issues.dlang.org/show_bug.cgi?id=15221 Issue ID: 15221 Summary: Duration should treat division by 0 as a logic error rather than throwing an exception Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: issues.dlang jmdavisProg.com Duration should never have checked for division by 0 and thrown a TimeException when it occurred. The OS/hardware already checks for that, and it should be considered a logic error. Checking for it and possibly throwing just slows the code down and makes it so that it can't be nogc. This is technically a breaking change, but it will only break code which doesn't bother to avoid dividing by 0 and then catches TimeException when it occurs, and such code is likely extremely rare, if it exists at all. Given the fact that the odds of actually breaking code are extremely low and that this allows us to make Duration fully nogc except for toString, I think that it's worth the risk. --
