C++: ctors for structs?
C++: Since a struct is a class with everything "public", are default -ctors created and called? The reason I ask is to understand the overhead, if any, that C++ may have over C, when structs are used. An opinion I have heard is that classes have some overhead that structs don't, in C++, but I question this. ...

Visual Studio: How do I show all classes inherited from a base class?
In Visual Studio, How do I show all classes inherited from a base class? For example, in ASP.NET MVC there are several 'ActionResult' types -- and they all inherit from / implement the base class 'ActionResult'. It looks like unless you just 'know' that 'View' and 'Json' are valid 'ActionResult' types, there is no way you can easil...

How does one - without inheritance - override a class method and call the original from within the new method?
I found one source which successfully overrode Time.strftime like this: class Time alias :old_strftime :strftime def strftime #do something old_strftime end end The trouble is, strftime is an instance method. I need to override Time.now - a class method - in such away that any caller gets my new method, while the new me...

Are there any static duck-typed languages?
Can I specify interfaces when I declare a member? After thinking about this question for a while, it occurred to me that a static-duck-typed language might actually work.

Script for College Class Registration
