Thies reminded me of something that should be considered here; we talked
about
and alternative array syntax for overloaded objects where all the array
indices are
required in one "chunk" to be able to resolve an overloaded array lookup.
eg: in COM, if you have a 2-Dimensional SafeArray, and you want to lookup an
element, you need to provide both dimension offsets at the same time.
$foo = $arr[0][1];
This cannot be acheived with the current breadcumb evaluation used by the
engine, as the engine will try to resolve $tmp = $arr[0]; $foo = $tmp[1];
One of the possible solutions was the pascal style array indexing:
$foo = $arr[0,1];
If we overload [] too much, we really will end up with unmaintainable code.
I'm -1 on the alternative array declaration syntax unless we implement the
pascal syntax (or something else useful!) for ZE2 OO handlers, in which
case I'm -0.
