Without any doubt I highly recommend enrolling on Compilers course by Prof. Alex Aiken. Since I had some time to make preparations I decided to include skeleton project for NLT generator, and the way COOL assignments are organized made me refine some features of NLT.
Among others there is one which existence derives from limitation of C# — you cannot define
enum which inherits from the other
enum despite the fact the
enum in C# is strong alias of
int (and you can inherit classes containing
ints as you like). In other words if you have to define constant integer values gradually you have to use old boring
ints (and lose value safety).
I am far from reaching
enums in Skila but I won’t make the same mistake. Anyway, both frameworks — COOL C# and NLT — are uploaded and waiting for you!
