[PD] '$0' in messages again, another proposal?

Personally, I often use $0 in large "initializer" message boxes:

[;$0-foo 10

;$0-bar 50

;$0-baz 10


I like this better than creating dozens of individual [s] objects. The 
workaround is to use $1 instead and pass the $0 from a [float] object, 
but yeah...

It's also an issue when I want to create a message like this:

[read media/$1-$2.wav $0-buf-l $0-buf-r(

I basically have to append $0 to the incoming list and offset all 
dollars by 1:

[read media/$2-$3.wav $0-buf-l $1-buf-r(

It's just unnecessary mental overhead.

Of course, I could do this instead:

[list append read media/$1-$2.wav $0-buf-l $0-buf-r] -> [list trim]

But I find this ugly and unnecessary.

The message box syntax is often more convenient:

[;$0-array const $1(

Of course, I could just as well write

[const $1( -> [s $0-array]

but people are lazy :-)


IMO it is a real pain point. Otherwise this topic wouldn't come up again 
and again...
