Maybe.  If the conditional expressions themselve need to be nested, you
will either end up with unwieldy formatting

--8<---------------cut here---------------start------------->8---
if (…) {
else {
  if (…) {
  else {
   if (…) {
   else {
    if (…) {
    else {
      if (…) {
      else {
        if (…) {
--8<---------------cut here---------------end--------------->8---

or you'll need to explicitly repeat (and revert) the logical expression
from the former branches.

Achim.
