= Dynamic Type =

 * See: http://cobra-language.com/how-to/UseDynamicTyping/
 * "dynamic" is a keyword in Cobra.
 * Any kind of object, whether primitive, value, reference or nil, can be used where dynamic is expected.
 * "dynamic" is the default type of untyped object variables, method arguments and properties.
 * "dynamic" is *not* the default type for local variables which are statically typed as inferred by the right hand side of an expression ("i = 0" makes "i" an "int").
   * Of course, if the right hand expression is of type "dynamic" then so is the variable.
 * You can also cast an expression to dynamic with `<expr> to dynamic`.
 * Operations on dynamic expressions are late bound like in Smalltalk and Python.
