In "Programming Perl", there is an example of eval in chapter 3 that I do
not understand. It is on page 161. It reads:
Here's a statement that assigns an element to a hash chosen at run-time:
eval "\$$arrayname{\$key} = 1";
I know the \ creates a reference, and the $ is dereferencing $arrayname.
Why is he calling it $arrayname when he is assigning an element to a hash?
I am not understading the relationship between array and hash here.
Can anyone provide some details about what is going on here? Thanks.
