jesuashok has asked for the wisdom of the Perl Monks concerning the following question:
Hi Monks,
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
I know that In perl we can store any types of References using a single Scalar Variable;
like :-
$scale_ref = \$scalar;
$array_ref = \@array;
$hash_ref = \%hash'
I am devloping Modules which is going act as a Interface between many modules.
The requirement is as follows :-
* I want to make a Scalar Variable which has to hold only Array Reference.
For example :-
In the above example I want to make the $table_list to hold only Array reference.sub collect_all_users_from_tables { $table_list = @_; }
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.

But I am not aware of this. I hope monks will help me.

Without explicit check is it possible to bring that future ?ref(@_) ne ARRAY' { + Carp 'Only Array can be processed'; }
