- -1. The feature exists to allow adherence to PEP-8, "Limit all lines to a maximum of 79 characters.", without requiring runtime concatenation costs. I use it frequently when assembling and testing message strings, for instance.

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.
