## Motivation { #motivation }

Let's start with a simple example:

Calling this program outputs:

	var tok lex.ScanToken
	for {
		tok = p.nextToken()
		// We save the line number here so error messages from this instruction
		// are labeled with this line. Otherwise we complain after we've absorbed
