    Hi, I'm new to Ruby programming and I just upgraded from 1.6.8 to 1.8.0
    preview3. I noticed that I can no longer define global variables like
    $3somevar (an example of the error I get is attached below). Ruby 1.8
    seems to complain about the 3 following the $ where it was perfectly
    fine with it in 1.6.8. Is there a reason for this? Thanks.


    %ruby example.rb
    example.rb:1: warning: useless use of a variable in void context
    example.rb:1: syntax error
    $3somevar = "whatever"

  2. Hi,

    Your ruby is too old.
