You are using ruby 1.5?

  % ruby -ve 'A = 1; A = 2' 
  ruby 1.4.3 (1999-12-07) [i386-freebsd3.2]
  /tmp/rbv36504:1: warning: already initialized constant A
  /tmp/rbv36504:1: warning: already initialized constant A
  % ruby-1.5 -ve 'A = 1; A = 2'
  ruby 1.5.0 (1999-12-14) [i386-freebsd3.2]
  % 

Several months ago, Matz said that `constant' may be renamed to
`shared variable' or other name in the future.  I need a sort of
variable which cannot be redefined and I object to lack of `constant'
but I have not sent comments yet :-<

Do you want a warning for re-substitution to a `constant'?
