We use grammar files from PHP-Parser.

The following parts need to be done.

• #5
• #7
• #9
• #11
• #14
• #17
• #28

When starting work on each item, you need to create a separate issue with a description,
and the created PR must be marked as closing the created issue.
The description should have a link to the RFC, as well as a short description + examples.

All new tests should be written in files with the php8_1_test suffix using the tester package. If the package
does not contain the required test type, then it is advisable to write the test suite for it in a separate PR.
