Not quite.
my $ref = [EMAIL PROTECTED], [EMAIL PROTECTED];
creates a scalar as reference to an anonymous array, each of whose
elements is an arrayref.
my @array = \(@array1, @array2);
creates an array, each of whose elements is an arrayref.
In some cases, the second option may be more desirable, but they
aren't interchangeable:
my @array1_copy1 = @{$ref->[0]}; # arrayref of arrayrefs
my @array1_copy2 = @{$array[0]}; # array of arrayrefs
