[imp] $imp vs. $_SESSION['imp']

Hello,

I had written:

Because of the following remark in horde/imp/lib/Session.php:
> class IMP_Session {
>     /**
...

I had also asked:
>   Or perhaps $_SESSION['imp']$imp['cache']['knu']?

A typo. I had meant to write "$_SESSION['imp']['cache']['knu']",
Of course.

Thanks for the explanation given,
and best wishes,
