https://issues.dlang.org/show_bug.cgi?id=23234 Issue ID: 23234 Summary: Delegate literal with inferred return value that requires following alias-this uses class cast instead. Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: default_357-line@yahoo.de Consider the following code: class Bar { } class Foo { Bar get() { return new Bar; } alias get this; } void main() { auto foo = new Foo; void test(Bar delegate() dg) { assert(dg() !is null); } test({ return foo; }); } -vcg-ast reveals that the delegate is compiled to `return cast(Bar) foo`, rather than `return foo.get`. `test(delegate Bar() { return foo; })` works. -- |
