Discussion:
Paragraph 6, says "An instance of locale is immutable; once a facet reference is obtained from it, ...". This has caused some confusion, because locale variables are manifestly assignable.
Proposed resolution:
In 28.3.3.1 [locale] replace paragraph 6
An instance of
localeis immutable; once a facet reference is obtained from it, that reference remains usable as long as the locale value itself exists.
with
Once a facet reference is obtained from a locale object by calling use_facet<>, that reference remains usable, and the results from member functions of it may be cached and re-used, as long as some locale object refers to that facet.
