Subject: Re: determining whether an object is an immediate?

It is slow, but this is probably one of the better definitions
of what an immediate is - whether it exists in ObjectSpace or
not.

Here's another solution:

class Object;    def immediate?;false;end;end
class Fixnum;    def immediate?;true; end;end
class Symbol;    def immediate?;true; end;end
class NilClass;  def immediate?;true; end;end
class FalseClass;def immediate?;true; end;end
class TrueClass; def immediate?;true; end;end
