 The stuff<br>

that goes between the | ... | are variable declarations. For example<br>
this is sum for an array<br>
<br>
array =3D [1,2,1,1]<br>
array.inject(0){|x, y| x + y} =3D&gt; 5<br>
<br>
note the variable &#39;x&#39; and &#39;y&#39; are between the | ... | and t=
he action<br>
&#39;x + y&#39; takes place after. inject is expecting two variable to be<b=
r>
declared so that is another error.<br>
