+* Changes the `Class` type variable name to `Obj`.
+* Changes the `className` parameter name to `constructor` cause it represents [`class`][ts-classes] or [`function`][ts-function] constructor.
 * Fixes type variable `Obj` default value is set to [`Function`][function] by removing it cause it's always being picked from the `constructor` parameter.
