Better package system
There’s a problem in Ruby: what if your application requires two libraries and both of them require incompatible versions of another library?
API designers who are smart enough create a namespace for each major version (MyLib::API1, MyLib::API2 etc.) so that you can have multiple versions of the same code in run time.
There’s a better solution however. Io language does not make you to modify the global state: source code can be loaded in any other object. This means that you don’t have to pollute library code with a version-based namespaces but you still able to load as many instances of the library as you want. Just make sure you keep them in your private objects.
Dreams come true:
MyParser := Package load(“XMLParser”, “e1fc39a02d786”)
