Overview

This class restores a correct order of arguments after using a coerce method.

For example, expression "1 - symbolic" calls to Symbolic#coerce
which gives us a power to reverse a receiver and parameter of method
so we set a receiver as Coerced.new(symbolic) to reverse arguments back after coercing.
