Wouldn't that mean a null placeholder for the first popFront? 
That could be done though.

However I'm not certain I understand what you wrote, do you mean 
that in foreach loops popFront would be called first or do you 
mean that each time you call front or empty the popFront method 
is called beforehand?

I don't have much opinion about the former, but the later would 
be very problematic.
