Should "dispatch" be extended for timers?

[dunbarx at aol.com]

Hi.


"Send' can, er, send parameters as well as a command. In a button script:


on mouseUp
   send "putArg" && random(99) && random(99)  && "XYZ" to me in 5
end mouseUp


on putArg var
   put var
end putArg


You get pairs of random numbers and the text as well. All parameters come across as a batch.


Or you can separate in the usual way:
on mouseUp
   send "putArg" && random(99) & "," & any char of "ABCD" to me in 5
end mouseUp


on putArg var,var2
   put var2 --or the first one or both
end putArg

I love "dispatch", and the more I use it the more I find "send" murky.

With "dispatch" params seem more natural to me:

    dispatch "somecommand" to tSomeObj with tArg2, tArg2

But with "send" it's less clear how params are handled - here's an 
example from the forums today:

   send clearVideo LayerAlpha, baseLayer, LayerGraphic, \
      LayerAudio to me in 700 milliseconds

Seems like a good guess as to how it should be used, but of course the 
compiler complains.

So given that "dispatch" is also faster, why not use it for everything, 
extending it with "in" to allow timers:

    dispatch "somecommand" to tSomeObj with tArg2, tArg2 in 2 secs

Is there some reason I've overlooked as to why "send" allows timers but 
"dispatch" doesn't?
