@ -2190,7 +2190,7 @@ Array.wrap(0) # => [0]
This method is similar in purpose to <tt>Kernel#Array</tt>, but there are some differences:
* If the argument responds to +to_ary+ the method is invoked. <tt>Kernel#Array</tt> moves on to try +to_a+ if the returned value is +nil+, but <tt>Arraw.wrap</tt> returns such a +nil+ right away.
* If the argument responds to +to_ary+ the method is invoked. <tt>Kernel#Array</tt> moves on to try +to_a+ if the returned value is +nil+, but <tt>Array.wrap</tt> returns +nil+ right away.
* If the returned value from +to_ary+ is neither +nil+ nor an +Array+ object, <tt>Kernel#Array</tt> raises an exception, while <tt>Array.wrap</tt> does not, it just returns the value.
* It does not call +to_a+ on the argument, though special-cases +nil+ to return an empty array.
