In order to prevent any kind of confusion, let us remember the title of 
this post: "Making your own Definitions using Operators without built in 
meanings". In his post, Jerry asked for a way to obtain something 
equivalent to 

>>Del 'x' f_:=Curl[f] 

I gave him a solution: a notation with Del that is interpreted as Curl. And 
Jerry is right: in Mathematica "Del" is an operator without no built-in 
meaning. So, in Jerry private (and possible) world, "Del" can mean whatever 
he decides it to mean. 

And, of course, now that I provided a solution, anyone can change it, even 
without knowing exactly what TemplateBox means.
