Are we allowed to use 512-exclusive features like the

.?

operator or do we still need to maintain backwards compatibility?

not yet, when it's more stable, we will switch to 512 compile time features being allowed.

What the fuck does .? anyways

(a.?b) is roughly equivalent to (a && a.b), except `a` is only evaluated once (as though you stored it in a variable, if it was not already).

So it checks if say Weapon isn't null and weapon.force isn't either
?

Its ~slightly faster~.

it's also more elegant.

you can do

var/foo = bar?.dank

which is useful if your code is designed to handle foo being null

Nope.

511 is still supported as long as the define in compile options is still 511 and not 512

What is the official status of 512 support?
