How does Visula compare with other languages?
This question can be divided into two sections: language and notation. The language is actually very simple, and resembles Smalltalk, or even Simula. Due to the constraints of visual programming, the syntax needs to as simple as possible, to reduce the amount of visual clutter and input required by the user. Thus Visula is dynamically typed – types of variables do not need to be declared, rather they depend on the value actually assigned. Visula has no concept of global scope (except for the special std object), all classes in Visula are nested. This is intended to improve encapsulation. Another simplification Visula manages is the unification of the function and the class. A class is simply treated as a function that persists beyond its return. Apparently, this was first done in Simula. Methods are provided as nested functions, and actually all classes and functions are nested. Visula also supports class-variables, function pointers and pointer-to-method+object variables – they are al
