+Unequivocally the worst module I've taken on this course. The subject
+matter is fascinating, however the insistence on the use of this
+abomination of a language "Scala" completely ruins it. If you're going
+to teach something as complex as this, use a proper language, not some
+"object oriented functional" abomination. Use C, you know, the
+language that real compilers are written in. I will go to the end of
+the earth to dissuade others from taking this module so long as Scala
+is still being used.\\
