Thanks for soliciting wider review. Do you plan to summarise feedback from 
that list here? I think it is quite likely that I will unintentionally 
forget to check back and see if there are any useful suggestions.

On the subject of assert_NaN; I am quite happy to add that for the since 
being explicit is generally good. However assert_equals always failing 
when passed NaN would be a likely source of bugs. The two reasonable 
choices seem to be "throw" or "just work". I am not sure what is wrong 
with "just work". In particular I think it is quite obvious to anyone 
reading what assert_equals(NaN, something) does. Yes, it depends on a 
notion of equality that is a little different from the two notions of 
equality exposed by the ECMAScript == and === operators. On the other 
hand, the ES5 internal SameValue algorithm treats NaNs as equal so it is 
clearly not a totally alien concept.
