6649012e6c Produce error if <?= used as identifier 
Due to a peculiarity of how <?= is handled, it can get treated as
an echo identifier. Make sure it isn't, to match PHP behavior.

semi-reserved keyword.

0dd85ebd34 Support readonly before DNF type 
This makes us match the PHP 8.2 handling of readonly. Handling of
"readonly" functions is moved to the parser to allow distinguishing
them from readonly properties with DNF types. We have to uglify the
grammar to avoid some shift/reduce conflicts. Thank you WordPress.

f4ec6a1e53 Rename Scalar\EncapsedStringPart to InterpolatedStringPart 
It is no longer an expression node, which unfortunately does

0933986293 Make sure Array nodes can not contain null 
Now that destructuring is always represented using List nodes,
make sure that Array nodes can no longer contain null elements,
so well-typed code doesn't have to deal with them unnecessarily.

If an array does contain empty elements, these are now result in
an error and are represented as a ArrayItem with Error value if
error recovery is used.

The implementation is a bit tricky because at the time the Array
node is created, we cannot tell whether it will be used in a
creation or destructuring context. For this reason the error
reporting is delayed parsing has finished.

Closes #876.

13549aa794 Add support for first-class callables 
I'm somewhat unsure about the AST structure here.
VariadicPlaceholder is not a general expression. Maybe Arg->expr
should be Expr|VariadicPlaceholder? Or possibly the call arguments
should be an array of Arg|VariadicPlaceholder?

c758510a37 Add support for PHP 8.1 
With the introduction of intersection types, PHP now lexes the
token '&' either as T_AMPERSAND_(NOT_)FOLLOWED_BY_VAR_OR_VARARG.
This completely breaks parsing of any code containing '&'.

Fix this by canonicalizing to the new token format (unconditionally,
independent of emulation) and adjusting the parser to use the two
new tokens.

This doesn't add actual support for intersection types yet.

[PHP 8.0] Add attributes support (#661) 
Adds support for PHP 8 attributes, represented using `AttrGroup` nodes
containing `Attribute` nodes. The `attrGroup` subnode is added to all
nodes that can have attributes.

This is still missing FPPP support.
