As a gentle correction of fact, while folks have been *asking* for  
tail calls in the JVM for over 10 years, it's only in the last year or  
two that there's actually been support from VM implementors for their  
inclusion.  I've had specific discussions with JVM folks on this very  
topic on numerous occasions over the last 5 years.  [I can't speak to  
what other "basic features" might have been slated for inclusion  
"several years ago"; I'll note that invokedynamic has been slated for  
inclusion for much longer, but required some wrangling between  
competing VM implementors and language designers to actually settle on  
an implementable spec.  The result looks nothing at all like my memory  
of the original proposal.]

Back to your regularly scheduled Haskell discussion.
