Loop all pairs

Let's say I have this array:

{a, b, c, d, e}

How can I look through all the possible pairs?

a, b
a, c
a, d
a, e
b, c
b, d
b, e
c, d
c, e
d, e

Fictional language syntax please.

So why aren't your solutions as easy as >>8?
I mean if your language is going to be slow as shit it might as well offer the things that Python offer.
