Embeddable scripting language loosely based off of Lua

Objects are now separate from {} dictionaries the . operator now only indexes fields on objects, the [] operator can only be used on objects if the __index or __newindex functions are defined Additionally 4 new instructions have been added to the VM: OP_NEWDICT, OP_INDEX, OP_INCINDEX, and OP_NEWINDEX. The syntax to create a dictionary is as follows { <key> : <value>, <otherkey> : <othervalue> } eg. { "hello" : "world", "foo" : 1337 } The Lexer & Parser was extended to add the TOKEN_COLON ':' token. |

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
function __init(self)
self.vector = {}
self.x = 0
end
function __index(self, key)
return self.vector[key]
end
function push(self, val)
self.vector[self.x++] = val
end
function pop(self)
return self.vector[--self.x]
end
end
var vector = Vector()
for (var i = 0; i < 4; i++) do
vector.push(i)
end
for (var i = 0; i < 4; i++) do
print(vector.pop() .. " : " .. vector[i])
end

C API
The Cosmo C API is currently undocumented, however as soon as development has reached a stable state documentation on full language features and the C API will start.
