FunctionClosure -- the class of all function closures

Types of function closure:

• Iterator -- class for iterators
• MethodFunctionBinary -- a type of method function
• MethodFunctionSingle -- a type of method function
• MethodFunctionWithOptions -- a type of method function

Methods that use a function closure:

• disassemble(FunctionClosure) -- see disassemble -- disassemble a pseudocode or function
• frames(FunctionClosure) -- see frames -- get the frames associated to a closure
• localDictionaries(FunctionClosure) -- see localDictionaries -- get local dictionaries
• pseudocode(FunctionClosure) (missing documentation)
