They're useful, because they give you the instantiation chain, and it makes it 
clear why each instantiation is failing. Yes, what you ultimately need to fix 
is what's resulting in _error_, but that doesn't mean that the rest is useless 
(like knowing _where_ the template was instantiatied from and what arguments 
were used to instantiate it). If you don't want to see those, then use

grep -v _error_

on the compiler's output.
