Add more property types

Some of these are not maximally accurate due to lack of union
types.

Stop accepting strings as types

For types the use of a string is ambiguous -- it could be either
an Identifier or a Name. Don't guess.

Stop accepting strings as types

For types the use of a string is ambiguous -- it could be either
an Identifier or a Name. Don't guess.

Retain the implicit promotion to Identifier in places where only
Identifier is legal, e.g. various symbol names.

Specify more types

Use array<string, mixed> type for $attributes

Slightly more accurate, and stops PHPStan from complaining about
the missing array type information.

Add php-cs-fixer config and reformat

The formatting in this project has become something of a mess,
because it changed over time. Add a CS fixer config and reformat
to the desired style, which is PSR-12, but with sane brace placement.

Rename Expr\ClosureUse -> ClosureUse

This is not a real expression, treat it similarly to Node\Arg
or Node\Param.

The old name is retained as an alias for compatibility.

Introduce ComplexType base class

With the upcoming addition of intersection types, a type can
be Identifier|Name|NullableType|UnionType|IntersectionType, which
is quite the mouthful.

Introduce ComplexType base class

With the upcoming addition of intersection types, a type can
be Identifier|Name|NullableType|UnionType|IntersectionType, which
is quite the mouthful. Give NullableType and UnionType a common
base class ComplexType, which does not have any behavior, but
allows to write these types (and check them in instanceof) more
easily.

[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.

Add support for union types

We definitely need to introduce a general "Type" abstraction in
the next major version.

Avoid parent constructor call during node construction

Instead explicitly assign the attributes. This is a minor
performance improvement.

Add public visibility to getType method (#463)

Add explicit getType() methods

Rather than automatically deriving getType() from the class name.

Add strict_types to lib code

[cs] use PHP 5.4 short array, since PHP 7.0 is min version

Allow null in ClassMethod::getStmts()

Generate PHP 7 type annotations

Always use Identifier nodes

The parser will now always generate Identifier nodes (for
non-namespaced identifiers). This obsoletes the useIdentifierNodes
parser option.

Always use Identifier nodes

The parser will now always generate Identifier nodes (for
non-namespaced identifiers). This obsoletes the useIdentifierNodes
parser option.

Node constructors still accepts strings and will implicitly create
an Identifier wrapper. Identifier implement __toString(), so that
outside of strict-mode many things continue to work without changes.

Use null-coalesce operator

Update doc comments to be more specific

Now $stmts arrays really only contains Stmt nodes.

Add NullableType to types of properties/args that offer it (#323)

Fix returnType typehints

Fixes issues #207

Add a FunctionLike interface to Methods, Functions and Closures.

The elements listed above share common elements like parameters, possible return types and bodies.

Drop support for old Node format
