            a++++++++++++++++++++++++++++++++++++b - eat this!


	I am not convinced that a+++b should be resolved as (a++) + b. K&R
states that unary operators have a higher precedence than binary ops,
and that the former bind right to left.

	 Should not the above be disambiguated as a + (++b)?

	However it is well known that the semantics of a language and
its implementation by a compiler are not always the same ( shock! ).

	Our compiler (UNIX V) evaluates as (a++) + b.
	
	Have you tried a-----b ???

	Any programmer worth their salt, never meets these problems due
to their judicious use of spaces and parentheses!!!
