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

- (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.
