I define


MyFun[2 = 3]
still evaluated the argument and of course produces an error
I would like to get the unevaluated expression to be able
to separate the first argument.

In fact, I would like MyFun to be a macro which allows me
to play list processing games with the arguments.

How can this be accomplished?
