Bug 21387 – dmd.hdrgen - Wrong parent in pretty name for aggregate instantiated with lambda template

--- struct ChunkByImpl(alias pred) {} auto chunkBy(alias pred)() { return ChunkByImpl!pred(); } void main() { auto foo1 = () => chunkBy!((char a) => a == '_'); auto foo2 = () => chunkBy!((a) => a == '_'); import std.stdio; writeln("foo1: " , typeid(foo1()).name); writeln("foo2: " , typeid(foo2()).name); } --- Actual output: --- foo1: onlineapp.ChunkByImpl!(function (char a) pure nothrow @nogc @safe => cast(int)a == 95).ChunkByImpl foo2: onlineapp.main.__lambda2.ChunkByImpl!(__lambda1).ChunkByImpl --- Expected output for foo2: onlineapp.ChunkByImpl!(__lambda1).ChunkByImpl With QualifyTypes = true: onlineapp.ChunkByImpl!(onlineapp.main.__lambda2.__lambda1).ChunkByImpl
