Now this form makes sense!  But as you say, the Select(Identity) call is pointless so it
could be dropped.  Can I also write
  from p in EQ where p.Equals("any") != true
?

Try:

string r = MyExtensions.Reverse(s.ToUpper())
   .Trim().PadLeft('*', 9).Substring(1,5);

I do find it troubling that these extensions allow you to access Reverse without even naming
the class it is defined in.  This seems to be a great source of potential name polution.
What's going to happen after several classes extend string?
