+This library is header-only, and has a default dependency on Boost.Hana.  The
+Boost.Hana dependency can be eliminated, and `std::tuple` will be used instead

 <p>The single-character parser. The produced attribute is the type of the matched code point (<code class="computeroutput">char</code> or <code class="computeroutput">char32_t</code>). Used as-is, <code class="computeroutput">char_</code> matches any code point. <code class="computeroutput">char_</code> can also can be used to create code point parsers that match one or more specific code point values, by calling it with: a single value comparable to a code point; a closed range of code point values <code class="computeroutput">[lo, hi]</code>, or a set of code point values passed as a range. When calling with a range, only the iterators that bound the range are stored. Make sure the range you pass outlives the use of the resulting parser. Note that a string literal is a range, and that it outlives any parser it is used to construct. </p>
