    # item of interest as received by the corresponding calling form.
    # For a 'regular', i.e. unary, synchronous, non-long-running method,
    # it's the return value; for a server-streaming method, it's the iteration
    # variable in the for loop that iterates over the return value, and for
    # a long running promise, the user calls result on the method return value to
    # resolve the future.

    # The sample schema uses '$resp' as the special variable,
    # but in the samples the 'response' variable is used instead.
