<p>Aren't literals the only "constants" in C++? I think everything else are just variables who's types are qualified with <code>const</code> or <code>volatile</code> or such. While the name "variable" is unfortunate, much like "type variables" in type theory, it's a widely used term in C++.</p>
<p>IMO it would be cool to have a different icon in the Symbols sidebar for objects with different type qualifiers/specifiers, or maybe like a little lock or something next variables with immutable types.</p>
