All I'll add is that whether or not that specific example holds up today matters little to the wider point: which is, that the language makes promises, and you need to verify each claim due to the repeated [0] ambiguity/inaccuracies about them.
It is very easy to verify. Just have a working C compiler + git + make:
git clone https://github.com/vlang/v
cd v
make
./v your_program.v
On a modern machine with good network, it will take you under a minute, to have your own copy of latest V, and less than 200MB, including the .git/ folders.
You can also download .zip releases from https://github.com/vlang/v/releases , without needing git. The .zips there are <15MB, and contain a prebuilt V executable, so you do not even need make to use it.
