Hello, thanks for the precision.
Is there any reasons why scalac does not optimize general tail calls,
if, as it is shown in the paper, this is possible in Java ? It seems
to me that allowing unbounded recursion on tail calls is a central
feature of FP. AFAIK, it is required (by r5rs) for scheme
implementations. 

BTW, thanks for the great work done on scala !
