2.3 "Spread" Point Arguments to Functions

Many functions that take point arguments come in two forms: structured and spread. Functions that take structured point arguments take the argument as a single point object. Functions that take spread point arguments take a pair of arguments that correspond to the x and y coordinates of the point. [annotate]

Functions that take spread point arguments, or return spread point values have an asterisk in their name, for example, draw-line*. [annotate]
