Description:

This is a pure mimicri class.
It is not used by ST/X, but provided to support limited
compatibility for applications which walk codetrees,
knowing internals of ST-80's compiler class hierarchy.
This classes protocol is not (not meant to be) fully covering
the corresponding ST-80's classes protocol. It maps ST-80 messages
to corresponding ST/X messages (as far as possible).

This class was added to allow for the PD goody CodeReview to be filed
into ST/X.

NO WARRANTY and GUARANTEE; this class may be removed without notice.

Class protocol:

 new

(comment from inherited method)
return an instance of myself without indexed variables

Instance protocol:

 doAssignment: aNode variable: var value: val

 doBlock: aNode arguments: args body: seq

 doCascade: aNode receiver: rcvr messages: msgs

 doLiteral: aNode value: lit

 doMessage: aNode receiver: rcvr selector: sel arguments: args

 doMethod: aNode selector: sel primitive: prim block: block

** This method must be redefined in concrete classes (subclassResponsibility) **

 doParameter: aNode variable: var type: type

** This method must be redefined in concrete classes (subclassResponsibility) **

 doPrimitive: aNode code: code primitiveIndex: primNumber

 doReturn: aNode value: value

 doSequence: aNode temporaries: temps statements: stats

 doVariable: aNode name: nameString

 collectNodes: nodeList

 doNode: aNode

 doNodeList: firstNode

 doNodes: nodeList

cg: is it required to return the nodeList, or just sloppy programming?

 doType: aType
