It depends what you think if fine. Last time I checked Jython (Python
interpreter in Java) was just 10 time slower than Python. This probably
makes it unusable except for small scripts.
It do not even talk of tail recursion. A coworker used to Erlang tride
to program the same in other languages (such as Python). A tail
recursion loop killed the interpreter pretty quickly.
So yes, I think those implementations work as proof of concept, but I am
not sure that they are more than small toys, that will never be used in
When you get used to Erlang, you realized that its virtual machine is
superior to the JVM and it take a big part in Erlang success.
