Overview

Helpers for calling methods and instantiate class silently, even if there are arguments to be passed to constructor/method. The main idea is to try to guess the parameters, awaited by method, generate randoms for them and finally call the method on the singleton instance of this class.

#★ ⇒ Object

TODO:

Maybe we need to overwrite setter for this variable to avoid weird settings like String.★ = Fixnum.new

Note:

There is a possibility to explicitely set the singleton instance, in which case all the methods will be called on it.

Instance of a class, lazy initialized with guessed parameters. Cached.
