  I represent a receiver and its message.
 
  Precedence codes:
  1 unary
  2 binary
  3 keyword
  4 other
 
  If special>0, I compile special code in-line instead of sending messages with literal methods as remotely copied contexts.!

  !ParseNode commentStamp: '<historical>' prior: 0!
  This superclass of most compiler/decompiler classes declares common class variables, default messages, and the code emitters for jumps. Some of the class variables are initialized here; the rest are initialized in class VariableNode.!

  !Decompiler commentStamp: '<historical>' prior: 0!
  I decompile a method in three phases:
  Reverser: postfix byte codes -> prefix symbolic codes (nodes and atoms)
  Parser: prefix symbolic codes -> node tree (same as the compiler)
  Printer: node tree -> text (done by the nodes)
 
 
  instance vars:
 
  constructor
  method
  instVars
  tempVars
  constTable
  stack
  statements
  lastPc
  exit
  caseExits - stack of exit addresses that have been seen in the branches of caseOf:'s
  lastJumpPc
  lastReturnPc
  limit
  hasValue
  blockStackBase
  numLocaltemps - number of temps local to a block; also a flag indicating decompiling a block!
