Subject: regex/BNF for class names

Hi,

what's the regex or BNF for class names?
Are the allowed characters and sequences the same that are allowed for 
constants?

On
   http://www.ruby-lang.org/en/man-1.4/yacc.html
I can't find 'constant',
only
   class IDENTIFIER [`<' IDENTIFIER]
and
   IDENTIFIER is the sqeunce of characters in the pattern of
   /[a-zA-Z_][a-zA-Z0-9_]*/

, but AFAIK constants and class names have to start with an uppercase char.

So are class names
   /[A-Z_][a-zA-Z0-9_]*/
?

Or are more characters allowed?

Tobi
