What can it parse?
------------------
The parser supports parsing PHP 5.2-7.4.
The parser supports parsing PHP 5.2-8.0, with the following exceptions:
* Namespaced names containing whitespace (e.g. `Foo \ Bar` instead of `Foo\Bar`) are not supported.
These are illegal in PHP 8, but are legal in earlier version. However, PHP-Parser does not
support them for any version.
As the parser is based on the tokens returned by `token_get_all` (which is only able to lex the PHP
version it runs on), additionally a wrapper for emulating tokens from newer versions is provided.
