In fact, subscripting is defined in terms of addition and dereferencing. So:
Array[ index ] means *( Array + index )
Since addition is commutative, this is entirely equivalent to *( index + Array )
so, index[ Array ].
Or, an outrageous example:
"wombat"[ 3 ] means the same as 3[ "wombat" ] -- both mean 'b'.
Don't you ever dare code that!
