Hi all,
When I changed my variable declaration syntax from single to multiple
variables (int x, y) my project compiles but I get a weird parse
error:
$ ./Testcc ../med.cc
../med.cc
Parse Failed...
Tokens:
[...]
Testcc: Lexcc.x:(65,13)-(71,20): Non-exhaustive patterns in case
Any idea what causes this error in general? I understand what it means
in a Haskell context, but it doesn't make much sense to me as a parse
error.

Hi André,
I'm not sure what is causing the error without seeing the grammar. Can
you come to one of the lab sessions this week?
cheers,
Arnar
