It is very uncommon to use global locale as... about half of
programs will be broken as they not locale-aware.

(example boost::lexical_cast<std::string>(1024)=="1.024", 
 many developers would not expect this)

On the other hand when locale is used it would be imbued by default
to the newly created io-stream.

Additional point is the fact that there are may be many C++ locale
instances unlike the case of C locales.

So the **right** thing to do:

1. Use iostream's locale if you use stream
2. Use your own locale and provide imbue()/getloc() option as
   io-stream does.
