Hurl — shed (4)
I believe the answer is:
cast
This clue is a double definition.
'hurl' is the first definition.
(synonyms)
'shed' is the second definition.
(shed can mean to discard or cast off)
(Other definitions for cast that I've seen before include "Allot roles in a play" , "Register (a vote)" , "Complement of actors in a play" , "pitch" , "Play's actors" .)
