I just said the *representation* of closures could change.
You can determine exactly what should be in the lexical environments at compile-time; thus you can allocate a fixed structure of variables to hold the lexicals. I suppose that in theory, you might be able to implement an augmentable `the-environment' in guile-vm, but I do not plan on doing so myself. Or maybe so, I do have some old code I want to get back to at some point... http://ambient.2y.net/soundscrape/docs/tutorial/a-few-notes-on-music/a-new-vocabulary/ Andy -- http://wingolog.org/
