I created a stack using a LinkedList. This worked, but when testing it I 
found using,

writef("%s, %s, %s", stack.pop(), stack.pop(), stack.pop());

would present the stack as a fifo. I assume the results are because it 
is evaluating the arguments from right to left. Why?

The order of evaluation is undefined. In this case, the ABI of your 
architecture says function arguments are pushed on the stack from the 
right to left. Therefore, it is also convenient for the compiler to 
evaluate them in that order.
