Trying to create honest NSDecimalNumber in Wax

As I studied the issue I am facing in Trying to create NSDecimal in iPhone-Wax I am now aiming much lower. How can I create a fully functional NSDecimalNumber in Wax?

I have added the following two lines at the top of AppDelegate.lua in a fresh wax project.

local x = NSDecimalNumber:initWithString("2.3")
print(x)
print(x:class())

The output is

(0x631e054 => 0x631d1a0) 2.3
(0x631e924 => 0x25f618) NSCFNumber

instead of something like

(0x621e834 => 0x620c550) <NSDecimalNumber: 0x620c550>

Turning on full logging in wax give the following trace in the debug window:

Two things are showing in this log which I did not ask for, NSDecimalNumberPlaceholder and NSCFNumber. I believe these are the source of my grief and I have no idea where they are coming from. Any ideas on how to fix the issue?

Ultimately I want to call the method decimalValue, but wax complains that it can't call a method on a number.

NSDecimalNumber overrides -description to return the number it represents. When you're logging statement is printing "2.3", it is in fact printing the NSDecimalNumber object. You can verify this for yourself by calling -class on your x value and printing that as well.
