Just the other day, I was thinking that a preprocessor in PHP would be
handy. I've got a lot of code that goes
<?php
include 'cache.inc';
$c = new cache;
if ($c->uncached()) {
... main body of php code
}
$c->end(); // cache and/or display html
include 'stats_counter.inc';
?>
It would be nice to replace this with
<?php
START_CACHING;
... main body of php code
END_CACHING;
?>
but I can't see how this can be done neatly[*] with functions.

[*] It could be done badly with cache.php?inc=mycode.php where
cache.php is something like
<?php
include 'cache.inc';
$c = new cache;
if ($c->uncached()) {
include $_GET['inc'];
}
$c->end(); // cache and/or display html
include 'stats_counter.inc';
?>
