"worked exactly the same for each" made it sound as if you thought the
two expressions mean the same thing.  You do know they mean very
different things?

Yes, but that should not be news to you.  A much simpler example is the
classic 2D "array" that you can make using pointers (int **mat1) or by
direct declaration (int mat2[3][3]) and yet access both using
mat?[i][j].

What they mean depends on the types.  Since you have two different types
the meaning of the expressions are different.  This should have been
your point all along -- that the same expression means different things
depending on the type of the objects involved.

The same simple rules can be used to explain what each expression does,
but you are not keen on learning them.

*I* can tell, because I'd look at the declaration.  But you are right --
people who don't know C (or who don't take the declaration into account)
will be baffled.

It's very simple to do -- just make array values decay to pointer values
and define E1[E2] in terms of pointer arithmetic.  Then pretty much any
pattern of three *s or []s will give you a FooStruct.  Which one, of
course, depends on what is being indexed and what is being derferenced.
