I would like to create a reference to an array slice. Given the following code:
#!/usr/bin/perl
my @list = (0, 1, 2, 3, 4, 5, 6, 7);
print "@list\n";
my @short = @list[1..4];
print "@short\n";
my $ref = \{@list[2..4]};
print "@$ref\n";
Upon execution, I get the following result:
0 1 2 3 4 5 6 7
1 2 3 4
Not an ARRAY reference at test.pl line 7.
...which complains about the reference in the final
print statement.
Of course, I can take the indirect route of copying the array slice into another array of which I can get the reference:
#!/usr/bin/perl
my @list = (0, 1, 2, 3, 4, 5, 6, 7);
print "@list\n";
my @short = @list[1..4];
print "@short\n";
my $ref = \@short;
print "@$ref\n";
...but I would think that I could do this directly. Any illumination any of you would be appreciated. Thanks.
