Description:

node for parse-trees, representing self
This is a helper class for the compiler.

Class protocol:

 value: val

Instance protocol:

 name

 value: val

 codeForSimpleReturnOn: aStream inBlock: b lineNumber: lineNrOrNil for: aCompiler

 codeOn: aStream inBlock: codeBlock for: aCompiler

 codeStoreOn: aStream inBlock: codeBlock valueNeeded: valueNeeded for: aCompiler

not reached - parser has already checked this

 nodeDo: anEnumerator

helper for parse tree walking

 evaluateIn: anEnvironment

 store: aValue

not reached - parser has already checked this

 displayOn: aGCOrStream

Compatibility
append a printed desription on some stream (Dolphin, Squeak)
OR:
display the receiver in a graphicsContext at 0@0 (ST80).
This method allows for any object to be displayed in some view
(although the fallBack is to display its printString ...)

 printOn: aStream indent: i

 isSelf

return true, if this is a self-node

 acceptVisitor: aVisitor

Double dispatch back to the visitor, passing my type encoded in
the selector (visitor pattern)
