To use no encryption, you'd pass a parameter <code><span class='Function'>⊢</span></code>. Or it might happen that you write a Choose (<code><span class='Modifier2'>◶</span></code>) expression where one of the cases should do nothing <code><span class='Function'>⊢</span></code>, or return the left argument <code><span class='Function'>⊣</span></code>.</p> <h2 id="in-tacit-functions"><a class="header" href="#in-tacit-functions">In tacit functions</a></h2> |
