Interesting. I absolutely hate that behaviour. Some compilers
do it and its a massive pain finding the first error and fixing
it then trying to find another, and another,  and then discovering
that fixing the first actually changed the second! It's much,
much easier IMHO to fix one thing at a time.

Of course the program should give useful hints as to what it is
expecting up front. But not give me a raft of error messages - my poor
brain can only cope with one at a time! :-0
