When a function is “used” (invoked) before being declared, and that function returns a value with a tag name, the parser must make an extra pass over the source code, because the presence of the tag name may change the interpretation of operators (in the presence of user-defined operators). You can speed up the parsing/compilation process by declaring the relevant functions before using them.

PointA and PointB are arrays of at least 2 cells, containing coord x in cell 0 and coord y in cell 1.
