Perl variable indirection

[Parag Kalra]

Hi,

I have a function which looks something like:

sub foo_bar {
    ${$_[0]} = new foo_bar (
                              address => $_[1],
                              sudo    => $_[3]',
                              id      => $_[0] . '_' . $_[2],
                        );
        sleep 8;

}

When the code is executed, I get an error

 *Can't use string ("some") as a SCALAR ref while "strict refs" *

This is resolved using - *no strict 'refs*';

Do we need to always use the above while using Perl variable indirection
- ${$_[0]}
