    Clearer approach to defining active <
    
    As we know that "<" will be the active char required here, we can
    set up the code to have it active 'up front' rather than needing
    \char_set_active_eq:NN. For a case like this, where the char is
    hard-coded, that seems the best approach (and it makes the syntax
    clear in the code).
