Variant

Godot's tagged union type.

Primitives, Godot core types, and GodotObject-derived classes can be stored in a Variant. Other user-defined D types can be made compatible with Variant by defining to!CustomType(Variant) and to!Variant(CustomType) functions.

Properties and method arguments/returns are passed between Godot and D through Variant, so these must use Variant-compatible types.
