-To be completed, here are some notes:

--- mprog 31404
-function a_function( arg1, arg2 )
-  say("Arg 1: "..arg1)
-  say("Arg 2: "..arg2)
-  return 3 + 5
-end
--- mprog 31405
-target_mob = getmobworld(31424)[1]
-target_mob:loadprog(31404)
-target_mob:loadfunction( function()
-  a_function( "test1", "test2" )
-end)
--- alternate mprog 31405
-target_mob = getmobworld(31424)[1]
-target_mob:loadfunction( function ()
-  loadprog(31404)
-  -- alternately: target_mob:loadprog(31404)
-  -- alternately : mob:loadprog(31404)  -- 'mob' in this case would be
-target_mob because this function runs in target_mob's env
-  a_function( "test1", "test2" )
-end)
--- mprog 31405 with return value
--- note, 'mob' is not a function variable, but a global variable to the
-environment
--- uses closure magic to move values between script envs
-local result
-target_mob = getmobworld(31424)[1]
-target_mob:loadfunction( function ()
-  loadprog(31404)
-  result=a_function( "test1", "test2" )

-Not as pretty as something like target_mob:loadprog( 31404, "test1", "test2" ),
-but there is no straightforward way to implement args to loadprog directly.
-For instance, if I used the syntax above, by what name would you
-refer to those parameters in the 31404 script?
-So loadfunction is the way to do tricky stuff like this, for better or worse.
-I agree, it's often nice to have all the code in one place.
-loadfunction can't directly return a value, but you can use other tricks to
-get the job done:
-[code lua]
--- mprog 31405 with return value
--- uses closure magic to move values between script envs
-local result
-target_mob = getmobworld(31424)[1]
-target_mob:loadfunction( function ()
-  loadprog(31404)
-  result=a_function( "test1", "test2" )
-end)
-[/code]
