[Interest] QML compiler?

[Jason H]

I thought he V8 engine (which is used in Qt5) would have that feature already, since it gets a lot of performance by whole-method compiling the JS. However my understanding is the output of V8 is machine code, and therefore, not portable.And therefore, you'd need an intermediate layer, and how much slower is that intermediate layer than raw text? I'm guessing it's not worth it.

Yes, thought was given to that.

It doesn't exist yet.
