Re: Are comments safe inside notebook cells


6.0 doesn't make one improvement that would have been useful. Namely it 
throws away the comments when converting between various forms.

Here is an input cell:

f[x_] :=
 Module[{c = 3},
  (* Add c = 3 to x *)
  x + c]

Select the cell and use Ctrl-Shift-I or Ctrl-Shift-T to convert the cell to 
InputForm or TraditionalForm. The comment is lost.
