The <em>elements</em> of the list on the right have length 8, but BQN can't be expected to know you want to connect the two arguments in that particular way. Especially considering that if you happen to have 8 characters then the right argument <em>will</em> have length 8!</p> <p>There are a few ways to handle this. What we'll do is <em>bind</em> the place values to <code><span class='Function'>×</span></code> using the 2-modifier <code><span class='Modifier2'>⊸</span></code>. This modifier attaches a left argument to a function.</p> |
