The best example of that in Fortran 2003 is the PROTECTED attribute.
A casual reader of the standard is likely to believe that a variable
with the PROTECTED attribute cannot be modified outside of the module
in which it is contained.  A careful reading and the interps that
have been issued make it clear that PROTECTED is a promise made by
the programmer that he doesn't modifiy the variable outside of the
module.
