/**
 * GLS 3.2: The longest possible translation is used at each step, even if the 
 * result does not ultimately make a correct program while another lexical 
 * translation would.
 * 
 * This is fundamental to the way the lexer works. If there is a problem with
 * it, other tests (e.g. to test functionality of operators or identifier
 * names) would expose it quickly. Nevertheless, we test some combinations
 * here for consistency.
