[PRL] [plt-internal] Video of Clojure talk

I think you missed an earlier part of the talk that he quickly refers to 
in that comment. To expand out his point: the facility exists in Clojure 
now, but it uses up unbounded stack space and therefore isn't usable -- 
*yet*. But he mentioned earlier that at the JVM language summit he just 
went to, one language designer after another hammered on the desire for 
proper tail calls in the JVM. Based on the mood at the summit, he's 
optimistic that the JVM will eventually be properly tail-calling, at 
which point mutually recursive, tail-calling functions in Clojure will 
use constant stack space.
