String continuation

Hello!

Let's have a look at this little example code:

-module('strc').

-export([f/0]).

f() ->
    {["string1",
      "string2"],
     ["string3"
      "string4"]}.

This compiles fine and returns a tuple with two lists, the first with
2 strings, the second with a single list. Of course, if there was only
a typo in the second list (a missed comma), I wouldn't notice it until
the code executes (which might happen in an inconvenient time in error
handling code). I wonder that the possibility to omit the extra ++
from the end of "string3" line worth the problems what might be caused
by the missing comma. This only bit me once, so it might not be that
common...
