Bug 2244 – implementing a function with an alias is impossible

Following source: interface Intf { public void doIt(); } class Impl : Intf { public void impl() { /*empty*/ } public alias impl doIt; } void main() { (new Impl()).doIt; } Gives an error when compiled: main.d:5: class main.Impl interface function Intf.doIt isn't implemented The same happens with an abstract superclass, while it works when Impl doesn't extends Intf. While this is just a test case, I stumbled upon this trying to implement functions using a template, like: public alias EventHandler!(`mouseMove`, int, int) mouseMove; I changed the code back to use string mixins, but I'd love to see something like the above work.
