Re^5: Assigning value through references

i always use strict but got not no complaints as perl took it as a hash,
not a reference, but i remembered it would somehow work without arrows, like this
my $crd = ${$ref}{$key}{NAME};

`$ref{$key}{NAME}` and `${$ref}{$key}{NAME}` are two completely different things. But you can say that the latter is another form of arrow notation (the first arrow, because it's a dereference operator), so they are both a hash reference. `my $env = \%ENV; print $env->{SHELL}; print ${$env}{SHELL}; print $env{SHELL}; # barks under strict, undefined otherwise # output: /bin/bash /bin/bash` [download] Open source softwares?

$ref{$key}{NAME}

${$ref}{$key}{NAME}

my $env = \%ENV;
print $env->{SHELL};
print ${$env}{SHELL};
print $env{SHELL}; # barks under strict, undefined otherwise

# output:
/bin/bash
/bin/bash
