Re: size of an array ref

[moritz]

# array:
$ perl -wE 'my @a = qw/a b c/; say scalar @a'
3
# array ref:
$ perl -wE 'my $a = [qw/a b c/]; say scalar @$a'
3

that makes sense...I might have a reference to a reference to an array...I've tried a lot of permutations and not gotten '3'...is it possible to get the size of a ref to a ref?

[JavaFan]

      @array;
     @$arrayref;
    @$$arrayrefref;
   @$$$arrayrefrefref;
  @$$$$arrayrefrefrefref;
 @$$$$$arrayrefrefrefrefref;
@$$$$$$arrayrefrefrefrefrefref;
... etc ...

[brx]

$a= [1..10];$b=\$a;$c=\$b; $d=\$c;$e=\$d; 

$e=$$e while (ref($e) eq "REF");
print scalar @$e;
