Oh, you like to decide lexical ambiguities.  Well, I suppose you know a
bit of C++.  So what do you think this is:

*> int *foo ;

It's the declaration of a pointer to 'int' named 'foo', isn't it?  now
what's this:

*> x * y ;

*Obviously* this mulplies x and y and throws the result away, doesn't

Now look more closely.  Do you see it?  Or does it get more blurred the
closer you look?  We don't have this problem in Haskell, and in a sane
world, C++ shouldn't have it either.

If you find second-guessing the programmer funny, try to write a parser
for C++.  You will have so much fun, it's almost impossible to describe.

Even if you're on the right track, you'll get run over if you just sit there.
