hasLvalueElements checks whether you can pass the return value of 
r.front by ref and take its address. So, if you want to take the 
address of r.front, you should be using hasLvalueElements in your 
template constraint to prevent ranges which won't allow you to 
take the address of their front from being use with that function 
and resulting in compilation errors inside of the function.
