Ace Should be Counted as What?

In one of the games I’ve played, one of my friends had a King and an Ace. On the flop there was a 1 2 and 3. At some point, he said that counts as a straight as it loops but I disagreed. What do you think? Any comment?

Thank you.

Darren,

In any form of poker, a straight cannot loop. The ace can be used as part of the wheel (A-2-3-4-5) or broadway (A-K-Q-J-10). It is not permitted to complete a loop straight as in Rummy.
