 `create_function()` has been removed in PHP 8.

 The only usage of `create_function()` left is in a test situation for a
 test which - due to the deprecation of `create_function()` - is being
 skipped on PHP >= 7.2.

 I propose to change the use of `create_function()` to a closure and remove
 the test skipping on PHP >= 7.2.

 While not optimal as the closure would need to use `eval`, this change
 _should_ work and shouldn't cause any real world issues as the logic is
 only used within the test suite.
