Wow this is a fantastically useful function! Thank you for that, it's
definitely helped with my understanding of how scheme works, too.
Anyone else agree that this would be a very good addition to the snippet
repository?
Damnit David, I'm a musician not a programmer! In all seriousness though I
always do my best to figure out the answer myself via the documentation. I
know I've asked a far few questions over the past week but believe me there
are a lot that I've not posted because I've spent hours reading through the
manual and snippets. I'm very conscious about only using the mailing list as
a last resort instead of a short-cut to problems I could solve myself, and
I'm sorry if I've not given that impression!
