Ok, after looking at my code I discovered a huge problem with "first". 
("Last" is cool.) If all you do is implement them and use them with 
foreach, fine. But if you need to call them manually (which is the case 
sometimes), you get really badly interacting terms there. Look at this, 
taken from real code (the filter function):

while (!_input.empty && !pred(_input.first)) _input.next;

I can see the putative user scratching their head: "Ok, so I start 
iteration with the first element, then I move to the next one... but 
then why the heck am I looking at the first again?"

"First" must go.
