- fraction type renamed as FractionType and moved from operator-fraction.go to fraction-type.go - ListType moved from operator-list.go to list-type.go - all test file were renamed adding the "t_" prefix - defined a test template in file t_temple_test.go - new test file t_relational_test.go where relational tests are collected - lists can now compared as set using operators <, <=, >, and >= (IMPORTANT: here = menas same content, not same list)
