A similar problem lies with the parser used by expr(1). Most versions of
expr have a length operator used thusly:
              expr length <string>
However the string must not be any of the other expr operators. For example:
              expr length length
gives a syntax error. The problem is that the scanner knows about the
keywords and returns the token instead of the string.
