I don't like first/last. Given a sequence, its first and last elements are fixed (even if the sequence advances), i.e. first, head, toe and last have strict ordering to me.

Head/Toe is acceptable, but I don't like it either. Head has a well-known and unambiguous meaning, which is ok. But toe... (Being a non-native english speaker) I didn't even know its meaning until I looked it up in a dictionary. It sounds more like a head/bar pair to me (i.e. completely unrelated). "Collection's toe element" doesn't tell anything and it takes some time to recall term's meaning in this context (I got used to it a bit, though).

Other property I don't like about 'toe' is that it is shorter than its counterpart - 'head' - I think it should be the same or slightly longer.

That said, best names for me are left(most) and right(most), but they are not listed here :( May I vote for them?
