I have a patch that (at least for input files) makes this:

type file;

(file o) cat(file f) {
  app {
    cat "in.txt" stdout=@o;
    f < "in.txt";
  }
}

file a <"hello.txt">;
file b <"output.txt">;

b=cat(a);


turn into this kml (fragment):

    <vdl:execute>
      <vdl:tr>cat</vdl:tr>
      <vdl:stagein var="{f}"/>
      <vdl:stageout var="{o}"/>
      <vdl:arguments>
        <string>in.txt</string>
      </vdl:arguments>
      <vdl:stdout>
        <vdl:filename>
            <vdl:getfield path=""><variable>o</variable></vdl:getfield>
        </vdl:filename>
      </vdl:stdout>
      <vdl:inappmapping>
        <variable>f</variable>
        <string></string>
        <string>"in.txt"</string>
      </vdl:inappmapping>
    </vdl:execute>

However, I have no implementation of the <vdl:inappmapping> element. I 
guess its time for me to poke round at the guts of vdl.k a bit more.
