@Callable macro

Doesn't work inside an extension

The @Callable macro only works in your class definition, and will not work on Swift class extensions.

Gotchas

At the moment it seems like the Callable macro is broken if the function accepts Variant as a parameter.

See https://swiftongodot.slack.com/archives/C05BYJ95S5D/p1733424376946869 for updates.

@Callable func callable(_ variant: Variant) {
	GD.print("Called callable with \(variant)")
}
