What kind of apps would this help with?

JS is never going to take over on the server for me until it can compete with Python's statistics support, I didn't see much in these slides that suggests it could.

Node.js modules and apps that work with C++ libraries/services that return 64bit numbers. Not having 64bit integers is an issue.

Is the lack of bignums (more than int64) the real issue? JS has IEEE754 binary double so that's the same as in Python.

Library code can be cross-compiled a number of ways, so I wonder whether the blocker is the lack of Pythonic long.
