Let me second that. A few months ago I was looking at Ruby, Python, and MzScheme's GCs, and I found that Ruby code was hardest to read and badly commented. Python, on the other hand, was very nicely written and commented. Lua too, but Lua also has the advantage of being so tiny it's easier to read.
