Huh. No tailcall optimization? Then I don't understand something and have to recheck.

I just wrote a Redis REPL (wire protocol) parser using recursion. Being so simple, I wasn't worried about stack depth. But while stepping thru with WebStorm's debugger, I noticed the tailcalls were (apparently) being eliminated. An unexpected surprise.

Using nodejs 6.11.1, npm 3.10.10.
