(In reply to Colin Campbell from comment #11)
In the perl world using $x->{one}->{two} rather than $x->{one}{two} is the most common. one reason is that the arrow syntax can be used in a string e.g. print "Var: $x->{one}->{two}"
using the non-arrow syntax in this way does not do what you may think it does
Are you sure? I often use it,
use Modern::Perl; my $h = { foo => { bar => 'foobar' } }; say "my string with $h->{foo}->{bar}"; say "my string with $h->{foo}{bar}";
outputs:
my string with foobar my string with foobar
Without pausing fpr thought its not obvious which of the first three is doing what you want: #!/usr/bin/perl use feature qw( say ); my $list = [ 'foo', 'bar' ]; say "my string with $list[0]"; say "my string with ${list}[0]"; say "my string with ${$list}[0]"; say "my string with $list->[0]"; outputs: my string with my string with ARRAY(0x936cb8)[0] my string with foo my string with foo -- You are receiving this mail because: You are watching all bug changes.
