Well, the Haskell files are not the problem, they don't have to be built 
automatically. The point is that I want to call functions in a Haskell 
function if I get their names as strings. Isn't there any possibilty to 
do that? Eventually the interpreter reads also the console in to execute 
the input. Maybe it will be the best to look there (interpreter code of 

Thank you :)
