digitalWrite(array,1) bug?

Test performed on Espruino Original Board and STM F4 with 1v85.

var pins = [C7,C8];

digitalWrite(pins,0); // Sets both pins to low
digitalWrite(pins,1); // Only sets C8 to high

digitalWrite(pins[0],0);digitalWrite(pins[1], 0); // Works as expected
digitalWrite(pins[0],1);digitalWrite(pins[1], 1);  // Works as expected

Best regards,
Marten
