Yes.

The problem is when cgi["key"] wants to return an array.
Then "foo" == cgi["key"] will fail since you're comparing
a String to an Array.

So, I made CGI::Param subclass of String.  However, I defined
CGI::Param#to_a so if you want the array, you can have it and
then apply #each or whatever.

As convenience methods, I might suggest defining CGI::Param#each
etc.  Might be nice to have an ArrayLike mix-in instead of having
to define these methods, but I don't know how useful this is ...
