[gambit-list] clos-like system available?

[Kevin Smith]

Googling has revealed naught, so I ask the enlightened inhabitants of 
this list: do any clos or clos-like implementations exist which work on 
Gambit 4? I'm playing with Meroon right now but it has a few issues just 
getting it to load into gsi.

All the info I can find indicates that Meroon was ported to Gambit 3, 
but I was hoping it might work since it is the only lib I've been able 
to find.

Thanks,
Kevin
