You can also turn code into spaghetti without any unstructured branching constructs, just by judiciously using horrible coding practices in general. I submit to you a snippet from a perl script I wrote some years ago, which is just downright embarassing these days. Note especially the embedded SQL and HTML (with embedded javascript to boot) in the middle of my perl mere lines apart, the obscure variable names, the direct use of array members and references to them, the sloppy formatting, the ultra-long lines, and the painful use of the ternary ? : operator:

$ref=$dbh->selectall_arrayref("SELECT transc.id,transc.state,transc.st
+art_date,transc.phys_name,transc.mt_name,org.orgname FROM transc JOIN
+ org ON (transc.org_id = org.id) WHERE ( transc.state = 4 AND transc.
+qa_name='$userinfo{name}' ) OR ( transc.state = 2 AND transc.mt_name=
+'$userinfo{name}' ) ORDER BY transc.id");
foreach my $x (@{$ref}) {
  my $compdis = (filesexist($$x[0],"t") ? "" : qq{disabled="disabled"}
+);
  $$x[2]=~s/...$//;
  $selfjobs .= qq{<tr><td>$$x[0]</td><td>$whichtype{$$x[1]}</td><td>$$
+x[2]</td><td>$$x[5]</td><td>$$x[3]</td><td>$$x[4]</td><td><input type
+="button" value="Files..." onclick='window.location.replace("?fa=$$x[
+0]")' /><input type="submit" value="Complete" onclick='setja($$x[0],"
+complete")' $compdis /></td></tr>\n};
