Mtime comparison considered harmful (2018)
Current ideas to work around it require individual solutions per distribution/ISV, as this would mean they'd have to come up with domain specific criteria for cache invalidation (as the store path/derivation hash on NixOS) and to maintain a downstream patch for this solution and furthermore wouldn't work for local build processes (e.g. from within an IDE).
Lesson of the day: never use mtimes, they'll bite you in the ass sooner or later!

A new wave of Linux applications
I found a qmlcompiler folder at https://github.com/qt/qtdeclarative/tree/dev/src/qmlcompiler, but I don't know if it's the compiler itself or bindings. I can't find qmlsc in GitHub qt or qtproject though.

Enumerating and analyzing 40 non-V8 JavaScript implementations
Ok sweet I see now. They used JavaScriptCore until 2011 or so, switched to V8 until 2013, and have been using their own implementation, q4, since then. The source code seems to be here: https://github.com/qt/qtdeclarative/tree/dev/src/qml/jsrunti....
Thanks! Will add and be live shortly.

A Garbage-Collected Heap in C++, Shaped Like Typed Python
I implemented a GC in C++ a couple of years ago for a JS interpreter (some notes). Some of the optimization I spent a lot of effort on (NaN-tagging) might not be appropriate for your use case though, and I won't recommend using the exact same approach as I did.

Enumerating and analyzing 40 non-V8 JavaScript implementations
I made a toy ECMAScript interpreter a couple of years ago: https://github.com/mras0/mjs
Not really notable, expect perhaps being the only one on the list with an ES1 mode? :) (Can't promise it's accurate though, as it was hard to find examples).
Otherwise pretty boring (C++, hand-written parser, AST interpreter, ES1/ES3/ES5.1 support minus some regexp/timezone/locale stuff).
What are some alternatives?
