True.

I see!

Thanks for explanation.

Is @ the only problem?  How serious problem/inconvenience do you
consider it?

Would not it be possible somehow to rebind it again with some trick
along the lines of:

(de foo "Prg"
   (when (car "Prg")
      (run (let @ (up '@) (cdr "Prg")) ) ) )

Why this does not work?

Thank you,

Tomas
