I don't know why Google proscribes exceptions, but exceptions still have 
an uneasy relationship with C++. Older compilers may not support them 
properly, much C++ code uses them incorrectly and inconsistently, there 
isn't good support for exception safety or transaction safety, being 
able to throw value types is a big mistake, etc.
