that's it. only one module, which can be easily added to any project. no
need to modify the compiler in any way.

second thought i don't want to see that syntax.

it still looks like UDA, it *can* be completely substituted by one UDA
with string arguments, it adds hacks and special rules to the compiler.
no wander Walter says "no" for it.
