PHPC-2252
The signature of
Serializable::unserializewas changed in PHP 8: the argument was renamed from$serializedto$data, and a string type was added. Since users are unlikely to call this method manually AND be using named arguments on a single-parameter method, this does not have a significant downstream impact. The old signature is kept in place for PHP < 8 as adding the type would violate the original contract (which technically accepts any argument type).This also allows us to remove a workaround in the function map generation that was necessary due to the renamed parameter (see #1436 (comment) for discussion).
