that doesn't seem right, thunks can and do return value:
https://en.wikipedia.org/wiki/Thunk
Thunks are primarily used to delay a calculation until its result is
needed, or to insert operations at the beginning or end of the other
subroutine. They have many other applications in compiler code
generation and modular programming.
The term originated as a humorous, incorrect, past participle of
"think". That is, a "thunk value" becomes available after its
calculation routine is thought through, or executed.[1]
