Perpetual child's play (5,3)

I believe the answer is:

peter pan

I believe this clue is a double definition.

'perpetual child's' is the first definition.

'play' is the second definition.
(I've seen this before)

(Other definitions for peter pan that I've seen before include "Musical from Barrie play" , "J. M. Barrie play" , "Ever-youthful boy" , "Child that never grows old" , "ageless character" .)

I've seen this clue in The Guardian.
