test case: final class C { void m() { } } void main() { (new C).m; } Examining the generated code shows that m is a virtual function, and called using the class's Vtable. Needless to say, this is an unneeded slowdown.

This should also apply to methods that are declared final, whether in a final class or not. What happens here at the moment?

Looks like I managed to report a duplicate of this, #2326, which then got fixed in 1.037. *** This issue has been marked as a duplicate of issue 2326 ***
