in reply to using other variables as keys to hash

This is actually a bit of refrence-tastic syntactic sugar. Here is a working version :
print("$simpsons{father}\n"); 
print("$$string{mother}\n"); 
print("${$array[0]}{son}\n"); 
print("${$hash{family}}{daughter}\n");

The additional currlies clarify which potion is the hash reference, and which part is the key.

    There aren't any hash references in this example, just symbolic references. Running your code under use strict gives the following error:

    Can't use string ("simpsons") as a HASH ref while "strict refs" in use at ./test.pl line 11. --

      ok, but i think "HASH ref" means the symbolic reference was referencing a hash. you were probably correct in you're first post, that symbolic references are usually not a good idea.
