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.

I swear this is the special olypmics of computer programmin. In on corner we have the homo who can't come up with a correct programming solution. In the other corner we have the minimum wage toilet scrubber who doesn't seem to understand the difference between a combination and a permutation.
