From: Mayuresh Kathe Date: 2008-08-18T19:10:58+09:00 Subject: Immutable, Interned strings?? Hello, I'm learning Ruby via the "The Ruby Programming Language". The first chapter has the following statements; Ruby's hashes can use any object as a key, but Symbol objects are the most commonly used. Symbols are immutable, interned strings. What is the meaning of immutable, interned strings? Would like to know in common, general English :-) Thanks, ~Mayuresh
