    I agree. I'd like to see the form validation broken out, for
    example, into a validation library, that could be used to
    validate db inserts, remote form submissions, etc.

    I'm sure that some of the magic that goes into a vector graphics
    library could be applied to sundry problem domains.

    Again, flatter heirarchy.
