Handbook Note 42/113 Reusing Keywords

"Strict" isn't a keyword -- it's just a directive
(i.e., special meaning only in certain code
constructs). So its addition could have broken code
that had an instance field called "strict". (Granted,
you'd have to violate the convention of prefixing
fields with "F" to run afoul of this.)

"Operator" also isn't a keyword, though since it has
to follow "class", its addition would not have broken
any existing code.
