Could you give an example? We've tried very hard to avoid useless 
error messages, there should only be one error message for each 
bug in the code.
Parser errors still generate a cascade of junk, and the "cannot 
deduce function from argument types" message is still painful -- 
is that what you mean? Or something else?
