Arguments can be either functions or subjects, except for the rightmost one, which has to be a function to indicate that the expression is a train. Trains tend to be shorter than subject expressions partly because to keep track of this alternation in a train of all functions, you need to know where each function is relative to the end of the train (subjects like the <code><span class='Number'>¯1</span></code> above only occur as left arguments, so they can also serve as anchors).</p> <h2 id="practice-training">Practice training</h2> -<p>The train <code><span class='Function'>⊢></span><span class='Number'>¯1</span><span class='Function'>»⌈</span><span class='Modifier'>`</span></code> is actually a nice trick for getting the unique mask <code><span class='Function'>∊</span><span class='Value'>𝕩</span></code> from the self-classify <code><span class='Function'>⊐</span><span class='Value'>𝕩</span></code> without doing another search.
