Is there or will there be Static polymorphism?

Because most of the time you don't need runtime polymorphism you just want the concept at compiletime.
Static polymorphism is (zero cost abstraction) and gives you million times faster code.
 
Never heard about the term and so I can't say anything about it.
 
I thought when you overload a method, it is called Static polymorphism and the decision which method to call happens and compile time and so it is faster at runtime

Cerberus:
Class myClass

    Method myMethod:Int(a:Int)
        Return a + 1
    End

    Method myMethod:Int(a:Int, b:Int)
        Return a + b
    End
End

And when you override a method, it is called Dynamic polymorphism and the decision which method to call is happens at runtime and so it is slower

Cerberus:
Class myClass
    Method myMethod:Int(a:Int)
        Return a + 1
    End
End

Class myOtherClass Extends myClass
    Method myMethod:Int(a:Int)
        Return a + 2
    End
End

So, it is actually not how it works in Cerberus or did I misunderstood these terms and concepts?

:cool:Ah there's overloading, yes that's a version of static polymorphism that will do the trick perfectly.
 
The overhead is so much higher with runtime (dynamic) polymorphism.

Static polymorphism produces something like 1-2 pages worth of machine-code versus 8-9 pages if you use dynamic polymorphism. These kind of things are good to know because they hide behind the lines of code if you're not aware of it.
