<p>Hi together,</p>
<p>how do I use "<font face="monospace">Object.defineProperty</font>"
to add a new property to the '<font face="monospace">product</font>'
of a Rule? I've tried several things but most times I just get
some "<font face="monospace">undefined</font>" for the property
set.</p>
<p><br>

<p><i>Kind regards,</i></p>
