As far as I read the code in RC1 you can use only the type. But you can 
disallow (!) service implementations explicetly by naming their keys as 
an extra paramater.

I guess you read all those nice comments on

http://www.php.net/manual/en/function.register-shutdown-function.php ?

BTW in RC3.6 makeInstanceService() doesn't use a & before the function 
name. A comment asks "objects are passed always as reference - right?" 
The answer is no. Objects are always copied in 4.x unless you specfiy 
it. The function and the assignement need a &. Though in 5.0 this has 
been changed someway or other.

So you'd need a $obj =& t3lib_div::makeInstance($info['className']); as 
well.

PS: I changed once all occurences of "$obj = t3lib_div::makeInstance()" 
into "$obj =& t3lib_div::makeInstance()". Made makeInstance return a ref 
by adding a & and it worked out allright for 3.5. The only thing that 
broke was the extension manager or something else that had a weird class 
loading mechanism that worked via globals.

I can find the file in question if anyone is interested.
