Error presentation

[EagleoutIce]

When I enter code like this:

if(z > 3) 
   x;
else
   y;


print(k)

and request the dataflow graph, i get an error plastered into my face which just says that the code had a parsing error. Maybe we want a better error presentation and better text to show to the user?

And just to clarify: the parsing error is, of course, correct.
