== THINGS THAT MIGHT BE GOOD TO KNOW We'd rather not go changing the 'description' and 'base-test' files after having released them, but sometimes new information turns up. This is where we'll put it. * In 't1-description', it is left unspecified which kind of behavior infix:<%> has. There are a few ways to implement a modulo operator, based on how negative signs in the rhs affect the sign of the result, etc. Since we didn't specify it, you can assume any behavior for infix:<%> (as long as it is consistent). If you prefer us to specify it, let's go with Perl 6's behavior. * The 'base-test' files assume a 'perl6 -c' flag. The Rakudo b branch has one, and Niecza has one, but it turned out that Rakudo nom didn't have one. It now does, so if you're using the latest revision from the Rakudo git repository, you won't have a problem. * In 't3-description', it says "Write a program that reads numbers N from standard input, one per line", but 't3-base-test' is all about getting a single number from the command line. Go with the tests. * In 't4-description', the sentence starting with "If there is possible solution" should instead start with "If there is *no* possible solution", as the surrounding context indicates. * The fifth test in 't5-base-test' assumes a certain canonicalization of the tree with three nodes -- when in fact there are two possible canonicalizations. If your code gets the other one, feel free to change or ignore that test.
