Good question.  The API does not specify that they have to come back in 
the order that they appear, so one could argue that no.  The reason is 
also clear: during parsing, we prepend them to a linked list, and then 
access that list in-order later, so the order is exactly reversed.  But 
that's also not technically guaranteed by the API specification as 
written.  The code is (very slightly) smaller and easier to understnad 
for prepending then appending, OTOH if I read your question right, this 
seems to violate the 'principle of least surprise', at least for you...

So, is it a bug? Not in a narrow sense.  I could be convinced to 
document the issue, or if you have a very good argument for why a 
reverse-order list is not acceptable, it might be possible to convince 
me to 'append' instead ;-).

Happy hacking!
