BrowserUk,
Thinking out loud here with only the most elementary understanding of Perl internals - why can't you fake a closure? Basically increase the ref count without actually making the closure. You GC it by decreasing it. As long as you control the creation/modification/deletion of the hash keys and their values, I don't see an obvious problem?

Cheers - L~R
