Does Boost offer any facility for declaring basic_string literals in templates, i.e. something like

basic_string<CharType> s = BOOST_STRING("foo");

No, it doesn't AFAIK. Would this provide anything useful if it did exist? It wouldn't be a literal, since "basic_string" isn't a built-in type. That means there is no compile-time savings; a string object is still created and it happens at run-time. What advantage would it have over something like:

std::string s( "foo" );

If you really meant any "CharType" and not just "char", then a "BOOST_STRING" macro would have to reference a locale (probably the default global one) to perform a conversion.

I agree that "basic_string literal" is incorrect terminology. I should have asked, "How do I initialize an object of type basic_string<CharType> with a string literal?" Does Boost provide any nifty way of doing it? --Johan Råde
