[Tutor] Accessing Functions By Reference

[Lloyd Kvam]

somefunction is a reference to the function
somefunction() calls the function.

a = somefunction	# binds the name a to the function
a()	# calls the function

I've usually seen the ability to process functions using variables (i.e.
just another form of data) described as having "first class functions".
