        Why can't I do this:

        version( linux || OSX )
        {
           something common to each
        }

        ???


        This is not acceptable:

        version( MinGW )
        {
        version = linuxOrMinGW;
        }
        else version( linux )
        {
        version = linuxOrMinGW;
        }

        version( linuxOrMinGW )
        {
           seriously...?
        }


        Surely basic logical expressions within a version seem not only
        logical,
        but also very necessary?
        There must be a reason this is impossible, or else I can't
        believe it's
        not already like that...


    A workaround is to declare variables and use static ifs:

... these aren't acceptable work arounds, in this case, you're written a
whole module to subvert the insanity! :)
At bare minimum, the version list/map/table/whatever it is should be
exposed to static-if, without having to create a module like the one you
just described.

It is a workaround that works, regardless if you think it's acceptable 
or not, and I've already done most of the work so you don't have to.
