if..endif syntax
   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 C-5. Migration: old if..endif syntax | if ($foo);
    echo "yep\n";
elseif ($bar);
    echo "almost\n";
else;
    echo "nope\n";
endif; | 
 | 
   | Example C-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   Notice that the semicolons have been replaced by colons in all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).
