.init(include: EMPTY_ARRAY, exclude: EMPTY_ARRAY) ⇒ Object

Initializes StrictIvars so that code loaded after this point will be guarded against undefined instance variable reads. You can pass an array of globs to ‘include:` and `exclude:`.

“‘ruby StrictIvars.init(

include: ["#{Dir.pwd}/**/*"],
exclude: ["#{Dir.pwd}/vendor/**/*"]

) “‘ : (include: Array, exclude: Array) -> void
