Re^2: (another) HoH question

Almost there.

I added 'my %hash', and it cleared up the error in the assignments. But it still complains about '$hash->{$key}'. I thought this was covered in 'my %hash' as isn't $hash-{$key} pointing to %hash? What am I missing?

Thanks!

... isn't `$hash-{$key}` pointing to `%hash`? What am I missing? You're missing the point that the expressions `$hash{foo}` and `$hash->{foo}` refer to different and quite separate hashes. `>perl -wMstrict -le "my %hash = ( foo => 'bar' ); my $hash = { foo => 'not_bar_at_all' }; ;; print qq{what is foo? $hash{foo}}; print qq{what is foo? $hash->{foo}}; " what is foo? bar what is foo? not_bar_at_all` [download]	[reply] [d/l] [select]

>perl -wMstrict -le
"my %hash = ( foo => 'bar' );
 my $hash = { foo => 'not_bar_at_all' };
 ;;
 print qq{what is foo? $hash{foo}};
 print qq{what is foo? $hash->{foo}};
"
what is foo? bar
what is foo? not_bar_at_all
