Support for tail calls pretty much depends on the actual runtime implementation.

If it is important to you (it certainly is to me), use an implementation which supports proper tail calls.

I'm doing it and I have never looked back.

Out of curiosity, which implementation are you using?

This is very cool. Thank you!
