 A third way to think is to identify the lambda formula not with classes of alphabetic sequences, but rather with abstract structures that we might draw like this:
 
-<pre><code>&lambda; ... `___` ...
+<pre><code>&lambda;
+	... ___ ...
 ^      |
-|`______`|
+|______|
 </code></pre>
 
 Here there are no bound variables, but there are *bound positions*. We can regard formula like (a) and (b) as just helpfully readable ways to designate these abstract structures.
