28.3.3.1.5 Operators [locale.operators]
bool operator==(const locale& other) const;
Returns: true if both arguments are the same locale, or one is a copy of the other, or each has a name and the names are identical;false otherwise.
template<class charT, class traits, class Allocator> bool operator()(const basic_string<charT, traits, Allocator>& s1, const basic_string<charT, traits, Allocator>& s2) const;
Effects: Compares two strings according to the std::collate facet.
Returns: use_facet<std::collate>(*this).compare(s1.data(), s1.data() + s1.size(), s2.data(), s2.data() + s2.size()) < 0
Remarks: This member operator template (and therefore locale itself) meets the requirements for a comparator predicate template argument ([algorithms]) applied to strings.
[Example 1:
A vector of strings v can be collated according to collation rules in locale loc simply by ([alg.sort], [vector]):
std::sort(v.begin(), v.end(), loc); â end example]
