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?
There are situations where I see lots and lots of error messages caused by some detail that breaks the instantiability of for some function from std.algorithm.
While trying to find you an example, I have found and filed this instead :-)
