Array by value - (nf)

[Guy Harris]

The problem with the example you gave is that it was comparing the result
of the assignment operator (which is its LHS, i.e. a structure) with 0.
Structures and ints can't be compared; furthermore, structures can't be
compared because you can't just use a quick loop/string compare instruction
because it would compare any holes in the structure as well, so nobody has
implemented structure comparison.
