question about void, passing data and print\write

Forget the defines. Using IDE 1.0.2 you can make it work. Example:
HardwareSerial & lcd = Serial;

// function prototype
template<class T> 
void MyLCD(byte col, byte row, T t);

// function definition
template<class T>
void MyLCD(byte col, byte row, T t)
{
//  lcd.setCursor(col,row);
  lcd.print(t);
}

void setup ()  {  }  
void loop ()  {  }
That compiles without errors. I simulated the lcd class with a reference to HardwareSerial, but that's not important right now.

The important thing is to prototype the templated function as I did up there. Then the compiler won't generate another prototype in the wrong place.

this worked to a point, and i may be trying to do more than is possible(easily).

what didnt work is old way lcd.print(z[1],HEX); new way MyLCD(0,1,z[1],HEX); i get

CMSBridge_ino2.ino: In function 'void loop()':
CMSBridge_ino2:152: error: no matching function for call to 'MyLCD(int, int, byte&, int)'
