/* The usage "option.template get_value<bool>()" looks weird, but it's required
* by the C++ standard: "When the name of a member template specialization
* appears after . or -> in a postfix-expression, or after nested-name-specifier
* in a qualified-id, and the postfix-expression or qualified-id explicitly
* depends on a template-parameter (14.6.2), the member template name must be
* prefixed by the keyword template. Otherwise the name is assumed to name a
* non-template."
