And then we get something like

Debugger entered--Lisp error: (error "Attempt to modify read-only object")
  aset("isearch-forward" 0 111)
  eval((aset (symbol-name (quote isearch-forward)) 0 111))
  eval-expression((aset (symbol-name (quote isearch-forward)) 0 111) nil)
  call-interactively(eval-expression)

correct?
