#C++ types
Which Cfront are you teaching? Your readers will have 2.1, a bug-fix
version, pretty soon. So if you teach the bugs the compiler will not match
any more. I prefer to say what is right, and then discuss various
compiler's beefs with it. Such a feature is to be avoided in general use.
It's only the nitty-gritty details that have such problems. Not much to
worry about for a beginner's book.
