You would need to create a type to hold the delegate and use that as
your generic type argument instead of the delegate itself. Something
like
public class Test : Object {
public void delegate MyFunc();
private class MyFuncData {
public MyFunc func;
public MyFuncData (owned MyFunc func) {
this.func = (owned) func;
}
}
private List<MyFunc> funcs = new List<MyFunc>();
public void add (owned MyFunc func) {
this.funcs.append (new MyFuncData ((owned) func));
}
}
