Sorry, but this is not a good advice: var_export is not save for
recursive dependencies -> var_export($GLOBALS).
serialize is recursive dependency safe, but it sets the recursive
dependencies to NULL -> serialize($GLOBALS). It is not distinguishable
if a value is really NULL or a recursive dependency. This would lead to
incorrect dumps and would render HLI rather useless.

I agree as for PHP 5.1, but PHP 5.2 disallows access to
private/protected properties by reflection. As you can see here:
http://bugs.php.net/bug.php?id=40348&thanks=4 I already tried that way,
and the advise was to use var_dump() ...

I think it's not good style to change original PHP functions by
extensions, but I do understand that this makes sense for XDebug. But
would it be to hard to provide the original output in some different
function? Or to be able to disable the XDebug var_dump by
xdebug_disable()? Or something like this?
