jesuashok has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks,
I know that In perl we can store any types of References using a single Scalar Variable;
In the above example I want to make the $table_list to hold only Array reference. Because as module developer I may not aware who is going to use my module. But I need to take care those things in my module. In othere Languages like C or C++ character pointer contain only character pointer. I want the similaar things to be done in Perl also. I know that this can be done in perl But I am not aware of this. I hope monks will help me. I need some efficient way of doing this. This can be done by doing some explicit like Without explicit check is it possible to bring that future ?
