It's pretty unclear what its purpose is. The examples look somewhat like go (including something that looks like goroutines, right down to being called with `go`). So, what differentiates V from go, I guess? (Or whatever other language it views itself as competing with, if not go.)

#142Hm I looked around the repo, and there doesn't seem to be much there.

If you discount the lexer and parser, it's like 8-9K lines of code, and it's hard to imagine much being done there. You can make a "toy" in that much code, but the gap to a production compiler is very wide (e.g. a minimum of 50K or 100K lines of code).
There is also this translation which is not in the repo:
$ wc -l v.c
15099 v.c
Also, this bootstrapping part looks pretty slick, except I get a core dump (on Ubuntu 16.04 with default GCC):
$ time cc -w -o vc v.c
real 0m0.553s
user 0m0.517s
sys 0m0.035s
~/git/languages/v/compiler$ time ./vc -o v .

Compared to Go, taken from [1]
V is very similar to Go, and these are the things it improves upon:
- No global state
- No null
- No undefined values
- No err != nil checks (replaced by option types)
- Immutability by default
- Only one declaration style (a := 0)
- Much smaller runtime
- Much smaller binaries (a simple web server written in V is 65 KB vs 7 MB in Go)
- Zero cost C interop
- No GC
- Much faster serialization using codegen and no reflection
- Precompiled HTML templates unlike html/templates that have to be parsed on every request
- Fearless concurrency (no data race guarantee at compilation)
- Enums
- Generics (in July)
- String interpolation: println('$foo: $bar.baz')
- Stricter vfmt to ensure one coding style
- Centralised package manager

Where did you find `v.c`?
Re: The V Programming Language
#147It's amazing that one person can do all this. It really takes a huge amount of dedication, knowledge and high IQ to invent a language from scratch alone. I think he is trying to Rustify Golang which is a thing I always wanted to do before giving up entirely on Golang.

> No GC
How does that improve upon Go? Memory safety is much harder without a GC
