Original description

What steps will reproduce the problem?

1. I create a string function that return a String object or an char array

2.If I write it and I don't call it, it is compiled without errors instead I call it inside the loop this is the output

sketch_sep26a.cpp: In function 'void loop()':
sketch_sep26a:15: error: 'LightStateRange' cannot be used as a function

3. This is the entire code

void setup() {
  Serial.begin(9600); // initializa output to pc 
}

void loop(){
char  LightStateRange[]="";
String _l="";
_l= LightStateRange(30);
Serial.println(_l.length());

}

String  LightStateRange(int light){

String  _lightState="";
 /\* 0-25 Dark 
   26-70 Dark with moon
   71-140 Night with near civil light
   140- 300 Early morning or became night
   300 - 500 morning or afternoon
   501- 800 light
   800  bright
   900  very bright
   _/
   /_
   if (light==0 || light<=25 )    _lightState="Dark";
   if (light>=25 || light<=70 )   _lightState="Dark with moon ";
   if (light>=71 || light<=140 )  _lightState="Night with near civil light";
   if (light>=140 || light<=300 ) _lightState="Early morning or becaming night";
   if (light>=301 || light<=500 ) _lightState="Morning or afternoon";
   if (light>=501 || light<=800 ) _lightState="Day and light";
   if (light>=801 || light<=900 ) _lightState="Bright";
   if (light>=901  )              _lightState=" Very Bright";
   */
  return _lightState;
## }

What is the expected output? What do you see instead?
