https://issues.dlang.org/show_bug.cgi?id=19541 Issue ID: 19541 Summary: Confusing error message about missing opEquals for AA key Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: acehreli yahoo.com struct S { bool opEquals(ref const(S) that) const { here_is_a_compilation_error; } } struct T { string[S] aa; // <-- Compilation error } void main() { } Error: AA key type `S` does not have `bool opEquals(ref const S) const` The message is confusing because the AA key type S satisfies what it says. Apparently, the problem is actually with a compilation error inside that function but the user is fooled by the message and is now looking for unnecessary workarounds instead of fixing the compilation error.
