I remember the discussion and I understand why `message` was templated to
allow wchar_t keys.  But what I don't understand is why the templated
`basic_message` lost one of its coersion (conversion) methods in the
process?

In other words, why these don't work:

std::wstring(boost::locale::basic_message<char>("blah"));
std::string(boost::locale::basic_message<wchar_t>(L"wideblah"));
