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
