For sure, that's why I mentioned initialisation syntax: if you can't use
objects as array keys, you can't use an array literal to construct any
other object which uses objects as keys either, so they're always going
to look uglier:
Compare:
$map = new Ds\Map([]);
$map->put($object1, 42);
$map->put($object2, 69);
$map->put($object3, 39);
$map->put($object4, 101);
To:
$map = [
$object1 => 42,
$object2 => 69,
$object3 => 39,
$object4 => 101,
];
There's a bunch of other gaps, too: arrays are copy-on-write, can be
used in constants and defaults, etc. If we want people to use something
- anything - instead of arrays, these are the things that only the core
language can provide.
