"Hierarchy"?  Oh, you mean operator precedence.  In this case it's
simple: unary from right always has higher precedence than unary from
left.

Why?  Even if the compiler gets the precedence wrong (which is
unlikely), it would then have to dereference a struct.  I don't think
that any compiler has ever been able to do that without an error.

What, you think the compiler might otherwise parse it as LD([i].LinePtr)
and not give an error? :-)
