Object#acts_like?

A duck-type assistant method. For example, Active Support extends Date
to define an <tt>acts_like_date?</tt> method, and extends Time to define
<tt>acts_like_time?</tt>. As a result, we can do <tt>x.acts_like?(:time)</tt> and
<tt>x.acts_like?(:date)</tt> to do duck-type-safe comparisons, since classes that
we want to act like Time simply need to define an <tt>acts_like_time?</tt> method.
