I have a series of template text (straight ascii, \w characters only) files with fields marked as %%field%%. Each field on a line will be unique but multiple fields may occur on a line. What regex can I use to list all the field names on a line? So far I have this working code but I'd be interested to see if there is a more general solution for n field names. 
    foreach (@fields) {
      m/%%(\w+?)%%.*%%(\w+?)%%/;
      push @matches, $1, $2;
    }
