Cavy is an object-oriented esoteric programming language, where everything is an object.

Hello world in Cavy:

System ctx {

    ^console->out: "Hello, world!".

}

interpret & run the code file with

cain file_name.cavy

Everything is an object?

Right. Your code declared in {curly braces}, namespaces, object attribute keys, everything except the basic keywords (there's only two: ctx and obj). Of course this poses a problem: how can we define any data type if everything we got is an object. The "primitive" data types are built from a special definition of natural numbers (slightly modified von Neumann numerals ):

{ {}: {} } = 0
{ {}: 0 } = { {}: { {}: {} } } = 1
{ {}: 1 } = 2
and so on...

They're called "raw numerals" in language, and by default, it is what the number literals return. A similar thing happens to the strings too - they're encoded naively as { index: charcode }, so for example { 0: 65 } is equal to "A". Yes, all of that is terribly inefficient.

Protection mechanisms?

None. You can reassign any default object (including System), any object attribute.

What's the point?

There is no point really. I wanted to see and design a language where everything is a modifiable object, and as it turns out, its possible. The language is not designed to be fast or sightreadable, but rather to treat everything interally as an object
