https://issues.dlang.org/show_bug.cgi?id=23168 Issue ID: 23168 Summary: [DIP1000] return scope wrongly rewritten for structs with no indirections Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: Ajieskola gmail.com Compile with dmd 2.100.0 and -preview=dip1000 switch. --------------- struct Ptr { safe int* fun() return scope {return null;} //int* aRef; uncomment to compile } safe int* use() { Ptr ptr; return ptr.fun; } --------------- The compiler detects that Ptr has no indirections, so it correctly judges `return scope` as needless. However, instead of just removing it, it replaces it with `return` attribute. This makes this code to wrongly fail to compile. --
