Why I like Smalltalk: lots of reflection
From a recent post by Travis Griggs ....
p := 4 @ 3.
p changeClassTo: (p class copy superclass: p class).
p class methodDictionary at: #negated put: (p class methodDictionary at: #transpose).
p negated
Amazing. This creates a new anonymous class for the Point, and mucks with the method dictionary. At runtime. Yum.
