Alternatively, you can allow a larger language and do some manual error
checking in the parse tree.
I'd like to see some data on how hard it is to make various languages
LALR(1). I already know that C++ is extremely ugly in this respect, and
that C isn't pretty but doable. What about other well-known languages
(Java, Perl, Pascal, name-your-favourite)?
