A brief reading of the Smalltalk-80 "Blue Book" has left me with quite a few questions. I would welcome comment on the truth or fallacy of the following statements. ---------------------------------------------------------------- Variables are a special entity in Smalltalk that, without being Objects themselves, refer to Objects. Variables are typeless in the sense that [zap <- #(1 2 3). zap <- 3.7654. zap <- 'string'] is a legal block which would leave zap with the value of 'string'. (Or perhaps variables are strongly typed -- all being of type Object) Arguments passed to a Receiver are passed by value and not by reference. -Neil-
