they are actually accessable by the user. This approach is convenient,
because it allows easy access to an items contents. On the other hand,
it is memory and time consuming.

The streaming API allows you to trade a little bit of convenience for
optimal performance and and a low memory profile. Additionally, the
API is more lightweight, thus easier to understand.

Now we are ready to parse the request into its constituent items. Here's
how we do it:

That's all that's needed. Really!
