Witam,
 Hash w Perlu rzeczywiscie

  hash==associative arrays

 ale definicja _hash table_ jest szersza niz hash w Perlu.


--------------
"PERL 5: How to" , 2nd edition 1996 Waite..

1.3 Asociative arrays 
Asociative arrays are indexed by string values instead of by an 
integer index value. (...) Associative arrays, unlike scalar arrays, 
do not have a sense of order. (...) You can list the contents of aan 
associative array using one of three functions: keys, values, each. 
(...) 
1.4 References (...)
Array reference 
 You can create an array reference by using the backslash operator 
 (\) on an existing array variable. (...) 
Hash references 
 You can create a  HASH REFERENCE by using the backslash (\) operator 
 on an existing  HASH VARIABLE.
(...)
Anonymous Hash References
 Anonymous HASH, OR ASSOCIATIVE ARRAY, references are created the 
 same way anonymous array references are created.

Pozdrowienia
