global misses

[Robert Brenstein]

I am experimenting with optimizing some aspect of my program and 
noticed the following:

1. when a global is made into associative array, the globals() 
functions does not report its existence even though it can be used as 
expected.

2. the exist operator does not work with globals as objects.

Are these bugs or features?

I create a series of globals dynamically and use the globals() 
function to find which were created and delete them when they are not 
needed. However, after converting some of them into array, they 
essentially disappear from my scope. The second surfaced when I tried 
to rememdy the situation by checking for existence of a global.

It seems I either can't use associative arrays with globals or I must 
forget about removing them from memory.
