Issue ID: 21540 Summary: Cannot pass associative array of function pointers to const AA parameter with lower attributes Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: qs.il.paperi...@gmail.com As an example, an associative array of @safe function pointers cannot be passed to a function taking an associative array that has its value type the const version of the corresponding @system function pointers. void f(const(void function())[string] aa) { } void main() { void function() @safe fp = { }; void function() @safe[string] aa = [ "a": fp ]; f(aa); // error } For delegates instead of function pointers, the call to f compiles as it should. --
