Issue ID: 18503 Summary: Confusing error message for erroneous postblit Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: razvan.nitu1...@gmail.com This code: class C { this(this) {} } issues: test.d(3): Error: postblit can only be a member of struct/union, not class C Ok. Let's define a union with a postblit: union D { this(this) {} } output: test.d(8): Error: function `test.D.__postblit` destructors, postblits and invariants are not allowed in union D That's odd, you just instructed me that a union can have a postblit! Shame on you compiler! Spec: "Unions may not have postblits, destructors, or invariants." [1] [1] https://dlang.org/spec/struct.html --
