NSMutableDictionary Extensions

NSMutableDictionary extensions for Nu programming.

Declared in: objc/Nu.h

In Nu, NSMutableDictionaries are used to represent evaluation contexts. Context keys are NuSymbols, and the associated objects are the symbols' assigned values.

Methods

- setPossiblyNullObject:forKey:
- lookupObjectForKey:

-	(void)	setPossiblyNullObject:	(id) anObject
	forKey:		(id) aKey

Add an object to a dictionary, automatically converting nil into [NSNull null].

in objc/Nu.h

(id)

lookupObjectForKey:

(id) key

Looks up the value associated with a key in the current context. If no value is found, looks in the context's parent, continuing upward until no more parent contexts are found.
