Subject: class 'initialize' method not working ???

I'm baffled by this error, after a hour+ of experimentation with 
solutions. I assume it's a compiler error (right term in Ruby?), as I'm 
not even getting access to ruby-debug.

Code snippet:
=======
def main

  opdb = Open_db.new( [1,2,3] )

end

class Open_db
  def initialize( dblist )   
    @dbs = dblist
  end

  @dbs.each do |cnt|  # <= line producing the error
    db_lbl = cnt[0]
    db_nm = cnt[1]
  end 
end

%w(rubygems ruby-debug readline strscan logger fileutils).each{ |lib| 
require lib }
Debugger.start
debugger # call to ruby-debug

main # ...initiate execution (at this point all dependencies are resolved)

# end file
=========

Error msg: setnet-xa.rb:12: undefined method `each' for nil:NilClass 
(NoMethodError)

It appears that @dbs is not getting initialized, but I cannot why not.

Any help would be much appreciated!

Tom
