-- The goal of the code below is to emulate OO method dispatch.
--
-- The use-case is binding to a C++ GUI framework that is heavily OO and
-- providing the user with a familiar experience.
--
-- This scheme sketched out below emulates not only OO style method dispatch
-- but also allows users to "sub-class", "override" and even arbitrarily
-- change the type signature of overridden methods, all without touching the
-- original library code.

This re-styles your sublime text sidebar to be dark, it fits default Monokai theme.

Save the Default.sublime-theme file into packages/Theme - Default, make a backup of your original if you want to be able to go back easily.
