yes, an other problem is, that e.g. [zexy] has to be created before 
[nop] ...

yes, two things about that:
- this should be local to each abstraction (otherwise reausability of 
abstractions is not guaranteed - there could be nameclashes ...)
- there should also be a way to not load all externs of a lib (like in 
python "import nop from zexy" or in C++ "using zexy::nop" ...)

(but I think we already discussed this ...)
