Also shuffles some method definitions and declarations to be more consistent with the way the Variant types are ordered across the codebase.
And removes an unnecessary JSON assign (`JSON::stringify` can now be accessed statically)
Hash comparison for Variant continues to perform semantic/logical comparison with NaN's considered equal by default (to prevent #16114, #7354, #6947, #8081), but now optionally allows for numeric comparison that does not consider NaN's equal to support proper value comparison (for #72222)
This is so everything is consistent, as a freed object is not equivalent
to `null` in general. The booleanization of a freed object still returns
`false` to work as an easy check for validity of objects. Similarly, the
negation of a freed object returns `true`.
Also makes freed objects different from each other (if they are not the
same reference).
- Consider PackedArrays non-shared since they are copied on C++/script
boundaries.
- Add error messages in the analyzer when assigning to read-only
properties.
- Add specific error message at runtime when assignment fails because
the property is read-only.
* Fix potential crash when using bind in `Variant::get_callable_error_text()`
* Properly compute bound arguments so they can be properly shown.
* Add a function to obtain the actual bound arguments.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Tweaks comments around the touched-up parts. Also tweaks spacing
Also adds some spacing in all cases of Variant::`reference()`. This is a special for consistency, because it ends up making the cases more readable.
- Add leading and trailing spaces within dictionaries, as the `{}`
characters are hard to distinguish from `[]` on some fonts.
This is especially helpful with empty arrays and dictionaries.
- Use different syntax for object printing to avoid confusion with arrays.
- Print null as `<null>` to avoid confusion with a string `"null"`.
- Display `<empty>` in editor resource pickers to avoid confusion
with array-based properties.
Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
For this to work safely (user not call queue_free or something in the expression), a const call mode was added to Object and Variant (and optionally Script).
This mode ensures only const functions can be called, making it safe to use from the editor.

When a type is shared (i.e. passed by reference) it doesn't need to be
called in a setter chain (e.g. `a.b.c = 0`) since it will be updated in
place.
This commit adds an instruction that jumps when the value is shared so
it can be used to skip those cases and avoid redundant calls of setters.
It also solves issues when assigning to sub-properties of read-only
properties.
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)
