-## Merge arrays of objects together, matching on a key
-It's a complex command, the trickyness comes from needing to have the right context in the expressions.
-First we save the second array into a variable '$two' which lets us reference it later.
-We then need to update the first array. We will use the relative update (|=) because we need to update relative to the current element of the array in the LHS in the RHS expression. 
-We set the current element of the first array as $cur. Now we multiply (merge) $cur with the matching entry in $two, by passing $two through a select filter.
