To be fair, by far the biggest help has turned out to be to get instant
compiler warning/fails while you type code. This has drastically reduced
the stupid typo, doesn't compile, try again cycle.

Code completion is 'cute' but I'm not really limited in typing speed,
getting pop-up function arguments while typing is useful.

The better code navigation is also very useful.
