      I don't believe functional decomposition and OO are at odds. Good OO
      designs have eschewed global or shared state for a long, long time. It
      just happens that functional languages make it more painful to do
      certain silly things (And less painful to do others.) I know I'm not
      the only one who thinks this way.

      I have always been a multi-paradigm guy. My languages of choice at
      various times have been: C, Perl, Ruby, JavaScript, etc. All of these
      provide more than one way to do the same thing. They can be made to
      behave as OO, functional, procedural, or a variety of other things
      depending on what makes sense at the time (They can even be refactored
      from one to the other.)

      I'm not sure what you mean since "static" can mean a variety of things
      depending on the context. For example I don't think the notion of
      class vs. instance methods matters much in distinguishing OO from
      functional. Shared/global state is a different matter.

      Shared and/or global state are a problem in massively distributed apps
      which more and more web apps need to be (Although in the 90s when Java
      emerged this was less true.) I think the real problem is that the
      libraries and tools typically used in languages like Java and C# lend
      themselves to big monolithic designs, but this is becoming less and
      less true as the needs of programmers evolve (e.g. check out the SE
      version of Restlet or the Play Framework.)

      I think that a lot of folks teach structured programming and call it
      OO, or they teach some marriage of the two. Java and C# were both
      conceived for the express purpose of allowing C/C++ programmers to
      transition easily, and C++ was itself a multi-paradigm (OO and
      procedural) language. I know a lot of Ruby, Python, and Smalltalk
      programmers who don't appear to have these same issues.
