https://wiki.php.net/rfc/short_closures#symbol_choice

In particular, note that this is already valid code:
[$x => $x * 2]
(A one-element array, specifying the key)

But with the proposal, this would also be perfectly reasonable:
[$x ~> $x * 2]
(A one-element array containing a closure)

So clearly they couldn't share the same syntax.
