Contexts

[plastpappa]

(dis is suggestion btw)

Contexts work a bit like environments - or, at least, they look and are meant for similar things. The current context can be gotten at any time from the var context. Here are the properties contexts would have:

• env or environment: Returns the environment living in the same place as the context.
• args: Returns the arguments passed to the function. If the context is not inside a function, returns undefined (or whatever Tulun's equivalent is).
• origin: Returns the context that created this context. If this is the top-level context, returns undefined (or whatever Tulun's equivalent is).
• top: Returns the top-level context.

Possible uses: Return value from parent function: context.origin.return("something"). Define globals from anywhere: context.top.var -> "something" Get variables from anywhere: someContext.environment etc.

I think they work great alongside environments. Maybe they're stupid and non-programming-like though. :P Discuss them.

:+1: Although, context.origin should return context.top when in the top-level, don't you think?
