Which brings us back to https://externals.io/message/64469
<https://externals.io/message/64469> from 7 years ago. And there is this:

<https://www.reddit.com/r/PHP/comments/budr7q/php_74_setters_and_getters_have_died/>
With getters/setters, it would seem Larry's proposal might allow for more
conciseness than it can with all other current syntax being the same as PHP 8.0
per Nikita.
Consider this, as one straw man type of new syntax:
class TimePeriod {
private int $Seconds = 3600;
public float $Hours {
get():float => $this->Seconds / 3600;
set(int $v) => $this->Seconds = intval($v*3600);
}
}
Or for a different use-case with different straw man syntax that could possibly
work in addition to above syntax, where externally $Balance is readonly whereas
internally Balance is treated like it is private so it can be set (I also used
Michal's ">" to indicate void, although I am not sure that using a greater-than
in a different context is a good idea):
class Account {
public get int $Balance;
public function Deposit(int $amount) > $this->Balance += $amount;
public function Withdraw(int $amount) > $this->Balance -= $amount;
}
