https://issues.dlang.org/show_bug.cgi?id=15707 Issue ID: 15707 Summary: Extend aggregate TypeInfo with information about `alias this` Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: public dicebot.lv Proposal: enhance TypeInfo so that for a struct like this: struct S { byte[8] x; int y; alias y this; } .. the following code will be valid: auto ti = typeid(S.init); assert (ti.aliasthis.offset == 8); assert (ti.aliasthis.next == typeid(int.init)); Use case: RTTI based formatting/logging, most importantly in cases where `alias this` struct is used as a replacement for typedef. --
