After reading my last blog about Kotlin with function, a lot of developers have asked me about, why with is not an extension to Template class like other scope functions?

Not only with, but run also has two implementations among which one is not an extension to Template class but a generic extension function.

The question is why?

with is an extension to generic class means it is not specific to any class. This could have been an extension to Any class which is the base class for all the classes, similar to java.lang.Object class in Java, even if you extend it or not. Or this could have been added as an extension to Template class which is compatible with Java objects also.
