Re: vim9script job function handler not recognized

Hi Bram,

I was inspired by testdir/test_vim9script...vim  and write these lines. 

I wonder how can this job can be monitored during its running life  maybe by callback or another job.

"

  # Zip command line

  @z = stampedDir .. archiveName 

  var archive_cmd: string = sevenZ.exe .. sevenZ.exclusion  .. ' a "' .. @z .. '" "' .. archiveSourcePath .. '"' .. sevenZ.compression

  # Zip's job

  var jobid: job

  var source: list<number>

  def Out_cb(...l: any)

      eval [][0]

  enddef

  def Exit_cb(...l: any)

sleep 1m

source += l

echomsg 'Exiting ' .. string(l) .. ' ' .. string(@z)

  enddef

  jobid = job_start(archive_cmd, { out_cb: Out_cb, exit_cb:  Exit_cb, mode: 'raw', timeout: 30000 } )

  echomsg 'jobid: ' .. string(jobid)

"

"cmd" is not defined. But you probably want to remove function() and
use MyHandlerCallback directly. The function will be defined
script-local, and using it as a string won't work inside job-start().

You don't need the ": void" for the function, not returning anything is
the default.
