You can also create an XMP object, with an optional binding to print
#==>42
#=> baz = 42

#=> foo = “bar”
END
baz = 42

Now, you can take advantage of the Object#xmp convenience method.

In order to use this library, you must first require it:

It’s much like the standard library PrettyPrint, that shows the value of each
