Hi Clemens,

Albert Reiner send a similar request on June, but i did not yet decide
whether it is worth implementing such a beast. His message is at
     http://www.engelschall.com/sw/wml/news/list/msg01713.shtml

Maybe you could explain why you need such a feature, it could help me
finding the best solution.

Note that wml::std::lang use a trick to perform the same action. In
fact, output files are always generated by wml_p9_slice, which has its
own syntax and shebang line. So the trick is to generate wml_p9_slice 
shebang lines during previous passes.
