to use an mighty hyper map capable of holding all informative "values" 
will just follow in the same amount of non-using code, and the using 
code will be filled up with info["blub"], info["blab"], evil castings, 
sensless const key-string an still no proper way to show/use the 
information in an generic and typesafe way

sorry but feels like throwing anway the signature conecpt and replace it 
with an runtime thing ... maybe we should also get rid of function 
signatures with "Variant[string] parameter" :}
