Subject: Re: ANN: vcard 0.1 - a vCard decoding library

I think the index method [] returning the preferred field (if pref is 
specified) or the first (of many) is acceptable.  I would not use the 
index method if I wanted a full enumeration (and you provide methods 
for that) but for quick access.  If you had two work email addresses 
(and none were preferred) I think as long as I get one, I would be 
happy.

if vcard[:email]
   ...send email
end

I would not want to have to always check for an Array vs. a String 
thought...that would make code kind of messy.
