Perhaps you're right. That was a bad example. One way CGI.pm shows its usefulness which seems to been obscured here is with deeply nested constructs (table within a table within a form, etc.).

By replacing the BEGIN/END (tag) paradigm with a nested function call paradigm, CGI all but eliminates the kind of unbalanced tag nuisances one frequently encounters when generating HTML dynamically.

IMHO, I find looking at naked HTML (in a HEREDOC or otherwise) annoying for its waste of space (I suppose XML rubs me much the same way) and its near-redundancy; I dislike typing it even more.

I suppose the advantage is better illustrated with this comparison:

<FORM METHOD='POST>
  <INPUT TYPE="hidden" NAME="mode" VALUE="confirm">
  <TABLE BORDER=0>
    <TR>
      <TD>
        <TABLE WIDTH='100%'>
          <TR>
            <TH>ColA</TH>
            <TH>ColB</TH>
            <TH>ColC</TH>
          </TR>
          <TR>
            <TD>Value A</TD>
            <TD>Value B</TD>
            <TD>Value C</TD>
          </TR>
          <TR>
            <TD><INPUT TYPE="submit"></TD>
            <TD><INPUT TYPE="reset"</TD>
            <TD>&nbsp;</TD>
          </TR>
        </TABLE>
      </TD>
    </TR>
  </TABLE>
</FORM>

Compared with:

form( { -method => 'POST' },
       hidden( -name => 'mode', -value => 'confirm' ),
       table( { -border => 0 },
               Tr( td( table( { -width => '100%' },
                              Tr( th( [ 'ColA','ColB','ColC' ] ),
                                  td( [ 'Value A','Value B','Value C' 
+] )
                                  td( [ submit, reset, '&nbsp;' ] ))
                            )))
            )

Oh, you want to write all that to the browser?

print form( { -method => 'POST' },
       hidden( -name => 'mode', -value => 'confirm' ),
       table( { -border => 0 },
               Tr( td( table( { -width => '100%' },
                              Tr( th( [ 'ColA','ColB','ColC' ] ),
                                  td( [ 'Value A','Value B','Value C' 
+] )
                                  td( [ submit, reset, '&nbsp;' ] ))
                            )))
            )
    )
