Using typeglobs it is possible to create constant scalars by saying something like *PI = \3.14159; I haven't been able to find any similar way to create constant arrays or hashes. Since taking a reference to a list is just the same as having a list with all the elements references, *LIST = \( 'a', 'b', 'c' ); is the same as *LIST = ( \'a', \'b', \'c' ); and just makes $LIST a constant to 'c' and doesn't change @LIST at all. Using an anonymous array instead of a reference to a list doesn't work either cause anonymous arrays are lvalues and not constants...

Does anyone know of a way to make constant array or hash variables?
