The reason I'm comfortable calling BSDScheme in particular a compiler is because ultimately you get a small binary you can bring to another machine without a runtime. Javac may get you bytecode, but you're still dependent on a JVM. This is the most useful distinction for most users, not if it compiles straight to assembly or not.

In the case of JSC, a binary is produced currently but it must be launched by a Node app. So it doesn't exactly meet my criteria. But being able to produce embedded V8 code will not be significantly more difficult for these examples. (Recreating Node's stdlib would of course be difficult but that's separate.) I'm hoping to have a Node-independent target soon.
