A definition such as this:
def Func()
job_start(['/bin/bash', '-c', ':'],
\ {'exit_cb': function('Callback', [42])})
enddef
results in `E117: Unknown function: Callback` (in Vim 8.2.2900).

I like that. It is explicit about the arguments and it allows me to
reorder the callback's parameters as I see fit. And yes, it works.
Thanks,
