You mean zparseopts?  OPTARG is a variable used by the getopts builtin.

You can't get that directly. If you use

zparseopts - -arg+:=arg

Then you get

arg=(--arg value1 --arg value2 --arg value3)

from which you have to delete the "--arg" elements yourself, e.g.

arg=(${arg:#--arg})

Is that close enough?
