Your snapshot includes two different interfaces and I would like to get
a consensus on what we want to support.
One part is the POSIX2008 explicit locale interface. Essentially, all
functions operating on locale-sensitive data get a version which has
the locale as explicit argument. E.g. isalpha(ch) -> isalpha_l(ch, l).
This is highly desirable for multi-thread applications or programs
dealing with input in different languages at the same time.
The second part is the Linux/Darwin Thread Local Locale interface.
Basically, this allows setting a locale for the current thread without
modifying the global (fall back) locale. IMO this is just insane and
repeating the mistakes of the original locale interface. I am strongly
in favour of *not* implementing this.
