To elaborate a little:
lucas = processRSS is an expression like any other:
lucas = processRSS
4 + 3
"My name is " + myName
!myBoolean
As with any other expression, it gets simplified first, and the
onComplete property takes on that simplified value.
In the case of the assignment operator (=), the expression simplifies
to the value being assigned (in this case, a reference to the
processRSS function).
Best to avoid this syntax entirely - I've seen it used as sugar, but
IMHO it's just confusing.
