when used in an app block something like:

 app { 
   myapp "-in" @filenames(myarray[*]) "-type" "fast";
 }

then @filenames needs to be able to return something that gets passed to 
myapp as multiple parameters, rather than a single parameter with spaces 
in it.

I think (?) that this is hard to do if @filenames returns a single value, 
from a SwiftScript-theory perspective (though I think in the karajan 
implementation, @filenames can return as many values as it wants?)
