Rails - Sep 2007 - Newbie question: what does string[:symbol] mean?

I found this in many rails source codes: string[:symbol]
<pre>''Some string''[:some_symbol'']<pre>
Can someone tell me what it stands for?

Thks

This is likely a Haah reference -- the string is the name of the Hash  
object, and the symbol within is a key.  For more on symbols, see:

Thanks Faisal,

I read almost all you can find about symbols and the string class, but I 
couldn''t find how this must be helpful. For example, in the Beast forum
source code, a lot of messages in the rhtml files are writen this way:
<h5><%= ''What is
Beast?''[:beast_sidebar_title]%></h5>
or
<%= ''A small, light-weight forum in Rails with a scary name and a
goal
of around 500 lines of code when we\''re
done.''[:beast_sidebar_body] %>

Is it something related to localization? Or can you access something 
with this symbol?

Yup, localization.  Beast uses the Gibberish plugin to this end.
