[Object] do | Manual

[Object] do

Activates 'chain mode'. If chain mode is active, all messages will return the recipient object regardless of their return signature.
Usage:


 a := Array < 'hello' ; 'world' ; True ; Nil ; 666.
 a do pop shift unshift: 'hi', push: 999, done.

 Because of 'chain mode' you can do 'a do pop shift' etc, instead of

 a pop.
 a shift.
 etc..

 The 'do' message tells the object to always return itself and disgard
 the original return value until the message 'done' has been received.
