 For the coursework in this module you are free to use any programming
 language you like, but I will show you all my code using Scala---I
-hope you have fond memories of Scala from PEP. But as said, you do not

-  were other languages that have been used previously in CFL. I
-  recommend to not use Java or C for writing a compiler, but if you

-Scala, which is 2.13.3. If you need a reminder of the Scala handouts
-for PEP have a look
