The `alternative' way to write if/elseif/else statements, using if();
   elseif(); else; endif; cannot be efficiently implemented without
   adding a large amount of complexity to the 3.0 parser.  Because of
   this, the syntax has been changed:
   
| Example D-5. Migration: old if..endif syntax | 
if ($foo);echo "yep\n";
 elseif ($bar);
 echo "almost\n";
 else;
 echo "nope\n";
 endif;
 | 
 | 
   | Example D-6. Migration: new if..endif syntax | 
if ($foo):echo "yep\n";
 elseif ($bar):
 echo "almost\n";
 else:
 echo "nope\n";
 endif;
 | 
 | 
   Notice that the semicolons have been replaced by colons in all
   statements but the one terminating the expression (endif).
