Yet he still plays Shylock (7)

I believe the answer is:

exactor

I'm a little stuck... Click here to teach me more about this clue!

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

I don't understand how the rest of the clue works.

(Other definitions for exactor that I've seen before include "Demanding person" , "One demanding and obtaining (something from someone)" , "He demands payment" , "demanding sort" , "Person squeezing" .)

I've seen this clue in The Globe and Mail.
