  La syntaxe de l'instruction while est la suivante :

|while_stmt ::= "while" assignment_expression ":" suite

  . Elle ne dit donc rien directement sur les opérateurs.

  Mais ":=" apparaît directement dans la syntaxe de l'instruction
  d'expression !

|assignment_expression ::= [identifier ":="] expression

  Il y a aussi un exemple :

|while chunk := file.read(9000):
|    process(chunk)
