The point of the warning is that you did not assign a value to the 
variable, not necessarily that the contents are unknown. You get the 
same warning for global variables if you only use them in a main 
program. Removing unnecessarily assigning an empty string to such values 
would be a job for the compiler (which it currently does not yet do).
