Thanks!

Yeah, hyphens are definately more idiomatic for a high-level Scheme API. 
For now, while these macros are developing, I decided to be conservative 
about changing the names; at some point it'll be clear what the "high 
level" api is and that'll be a good layer at which to switch to hyphens.

OK. I added a link to Ypsilon on the 'bindings' wiki page.
