removing it is a bad idea for the reasons already given, but requiring 
parentheses could help.

that is, the following would result in a warning or an error:

     L = ["first", "second" "third"]

but the following wouldn't:

     L = ["first", ("second" "third")]

     T = ("This is a line of text.\n"
          "This is another line of text.\n")

etc.
