Function object
In Ruby, several objects can be considered function objects, in particular Method and Proc objects. Ruby also has two kinds of objects that can be thought of as semi-function objects: UnboundMethod and block. UnboundMethods must first be bound to an object (thus becoming a Method) before they can be used as a function object. Blocks can be called like function objects, but to be used in any other capacity as an object (e.g. passed as an argument) they must first be converted to a Proc. More recently, symbols (accessed via the literal unary indicator codice_35) can also be converted to codice_36s. Using Ruby's unary codice_37 operator—equivalent to calling codice_38 on an object, and assuming that method exists—the Ruby Extensions Project created a simple hack.
Ruby Thursday
Ruby begins running weapons procurement scams against A.I.M. She partners with and becomes romantically involved with the Answer. After having stolen money from A.I.M. on five different occasions, A.I.M. hires the assassin Bullseye to kill Ruby. He uses her relationship with Answer to draw her out of hiding and throws the Rolling Stones album "Flashpoint" (which contains the song "Ruby Tuesday") into her chest apparently killing the biological portion of her body. The Answer saves her head after Bullseye leaves in hopes of reviving her later.
