CPunch 6126b50941 cosmoV_throw() now resets the vm stack as well
also a minor GC bug in cosmoO_newError was fixed.

i'm going to try to phase out cosmoM_freezeGC & friends
since that would cause hell with this new
error handling solution. the only thing still using it is the GC.

What is a 'cosmo'?

Cosmo is a portable scripting language loosely based off of Lua. Cosmo easily allows the user to extend the language through the use of Proto objects, which describe the behavior of Objects. For example the following is a simple Vector Proto which describes behavior for a Vector-like object.

proto Vector
    func __init(self)
        self.vector = []
        self.x = 0
    end

    func __index(self, key)
        return self.vector[key]
    end

    func push(self, val)
        self.vector[self.x++] = val
    end 

    func pop(self)
        return self.vector[--self.x]
    end
end

let vector = Vector()

for (let i = 0; i < 4; i++) do
    vector:push(i)
end

for (let i = 0; i < 4; i++) do
    print(vector:pop() .. " : " .. vector[i])
end
