[Tutor] err... list.pairs()?

[spir]

Excuse me for such a stupid question, I just wish to stop and lose my time 
searching for something that maybe simply does not exist.
I'm looking for the builtin function for sequences that would return a list of 
(index,item) pairs to be used in loops. analog to dict's items() function.
[I was writnig "for index,item in symbols.items():" when I had a doubt on 
'item', as this hardly refers to a pair in the case of sequences. So that I 
wanted to check... I have not found it yet ;-)]

Thank you,
Denis


PS: It /should/ exist!
