Subject: MatchData.each method.....no "next" ?

I've got a block of code:

process = proc { |str,val|
        process_hsh = { "String" => true , "Fixnum" => true }
        re = /\((.*)\)|\{(.*)\}/;
        m = str.scan( re )
        if( process_hsh["#{val.class.to_s}"] ) then
          m.each{ |v|
            next if( not v); #<-----------------THIS IS THE CULPRIT
            puts v
          }
        end
      }


But "v" is always put to the screen. The output I get is:

*
nil
*
nil
*
nil
*
nil

In my test case, I am expecting:

*
*
*
*

Does MatchData not take advantage of iterating via "next" ? Thanks,
