It had only something to trap all console-messages («posts») during the 
time it takes to handle a pd-message. You send a message through it, and 
the console-messages are trapped until the message «returns» (end of 
message-handling, not counting any [delay]ed things).

It can be nested : you can have an [unpost] in the main patch and have it 
send stuff to an abstraction that also uses [unpost], for example, and 
posts will be sent to only one [unpost], the latest one still active.

I also thought there would be something specifically for errors, but kept 
it for the future.

I had plans for a different error-messaging system because [unpost]-like 
solutions need parsing error messages. I thought of future error messages 
being regular pd messages so that you can use [route] to pick up error 
categories by selector. That would have been much closer to try/catch or 
begin/rescue in other languages (while not actually implementing the part 
that makes it hard to implement).
