Great tutorial Soma! Thanks for making it.

One thing I wanted to mention is that this syntax:

wire("fuel")->set("helper", $this);

has been replaced by this syntax:

wire('helper', $this); 
// or this: 
$this->wire('helper', $this); 

But of course your tutorial is correct in using 'fuel' since it would be compatible with past versions of ProcessWire too. Just wanted to mention it since I think the API is simpler if all getting or setting of API variables is just done through the wire() or $this->wire() functions. But the old syntax will always continue to work as 'fuel' is itself an API variable, but one that I figured makes more sense as an internal-only API variable.

Hi, Ryan, Soma

Just tried out Soma's original code with PW 2.5.1 and the old call to...

 wire("fuel")->set("helper", $this);

...failed: call to non-object. It worked with the updated code.

So the old call is not backwards compatible any longer?
