This doesn't work as you intended. The bareword FIXED_STRING in a hash access will be used as the string 'FIXED_STRING' , not as an expression that would evaluate the constant. To use the constant, you need to prevent it from being treated as a bareword. $persistent{$x}{+FIXED_STRING} is one possibility.
