Sun perhaps initially seductive for compilers (7)
I believe the answer is:
setters
'compilers' is the definition.
(compilers or setters of cryptic crosswords)
'sun perhaps initially seductive' is the wordplay.
'sun perhaps' becomes 'setter' (something which sets).
'initially' suggests taking the first letters.
The first letter of 'seductive' is 's'.
'setter'+'s'='SETTERS'
'for' acts as a link.
(Other definitions for setters that I've seen before include "Long-haired gun dogs" , "They are expected to point" , "Canine" , "people like me" , "Crossword compilers" .)
