Indeed some lucky escape (3)

I believe the answer is:

yes

'indeed' is the definition.
(agreeing)

'some lucky escape' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'YES' is hidden in the letters of 'lucky escape'.

(Other definitions for yes that I've seen before include "That's 27 [RIGHT]" , "Affirmative response" , "Confirmation" , "Affirmative answer" , "Certainly!" .)

I've seen this clue in The Sun.
