[lua] Creating a table without __fields__

[LordMZTE]

I need to call an extern Lua function which expects a table with very specific fields and does not allow any additional fields. I have the function declared as such:

typedef Options = {
    baz:Int,
};

extern class Foo {
    static function bar(opts:Options):Void;
}

When this function is invoked as Foo.bar({ baz: 42; }), this generates some pretty complex Lua code which ends up passing

{
     baz = 42,
     __fields__ = ...
}

It would be great if there was a way to write an expression that results in plain { baz = 42 } in Haxe.

As a workaround, this seems to work:

final x = { baz: 42; }
cast(x, lua.AnyTable).__fields__ = null;
Foo.bar(x);

There's some helper methods for working with tables : https://api.haxe.org/lua/Table.html

By default anonymous objects include the fields field so that reflection works consistently.
