Personally when I face such
false warnings in my code, I change the code to remove the
warning so that if a warning does make sense, I can notice
it.
I used to do the same but fund such practice dangerous. It often
resulted in poorer, less "natural" code, sometimes, albeit less
frequently, degraded performance (not necessarily on platform
reporting warning but another), or would even introduce bugs, if
major change was required. Not to mention the cost of looking for
balance between different warnings on different platforms and that
of regression testing. In short, more pain than gain.
These days I prefer to selectively disable warnings I don't agree
with (via command line options if possible, or #pragmas or similar)
... and very selectively enable warnings beyond some sensible level
(defaults + select few are usually okay).
I thought a reference
implementation would be written with such policy.
There’s no way I’m gonna
read each of the hundreds of messages to understand if it is
a mistake in my source code or a “shortcut” in boost
library.
In a multi-platform, multi-compiler version library this is often
difficult if not impossible to achieve. Not only one compiler might
warn you're not doing X and the other that you are doing it, even
different versions of the same compiler might disagree on whether X
should be done or not. Heck, even the same version might if you
compile against different language standards and/or dialects. I
would find imposing any such or similar policy counter-productive
and unjustified.
So this is my first user
experience. Not impressed at all. Boost will not be my
reference.
I, on the contrary, was impressed and still am after all these
years. As others mentioned, not only C++11 received an enormous
contribution from Boost, it is one of the few truly peer-reviewed
general purpose libraries with a huge deployment base that gives you
some assurance that many people have already found many defects that
were already fixed and you are unlikely to stumble upon one.
