http://d.puremagic.com/issues/show_bug.cgi?id=10276 Summary: Compiler pointlessly makes a struct nested even if it doesn't need to be Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: andrej.mitrovich gmail.com 09:40:41 PDT --- ----- import std.traits; unittest { /* static */ struct S1 { int x; } /* static */ struct S2 { this(int) { } int x; } static assert(!isNested!S1); static assert(!isNested!S2); // fails } void main() { } ----- There is absolutely no need to make a struct nested *unless* it needs the context pointer. The compiler seems to make it a nested type as soon as it has any function or ctor implemented. This seems like arbitrary behavior. This is a problem with structs defined within unittests, because they end up breaking template code in weird ways (for example nested types can't be used with T.init). Using static explicitly is of course the workaround, but it should never be a requirement. The compiler should prefer making a struct static *unless* it has to do otherwise. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
