I'm not sure this does what you believe it does. In any case you want
to read the perlreftut document:

Use the reference operator \.

my $x = \@array;

This will give $x a reference to the array @array so if you modify an
element of the array from $x it will also modify the original array's data.

Or maybe this one:


@array = qw (hi venkatesh whats up);

foreach (@array)
{
        $x .= "$_ ";
}
print $x;
#now $x contains hi venkatesh whats up

That leaves an extra space character at the end of $x.

$x = join ' ', @array; # no trailing space
