C string and D string are different, but it's not a bad idea to have 
string *literals* that works for both C and D strings, otherwise using 
printf will lead to a bug each time the programmer forget the trailing 
\0.

You can't rely on an empty string to be null since you must be able to 
reserve place at the end of the array, and or the string could be the 
result of poping a full string.
