How many useful projects never have more than one developer?
What is more likely to boost productivity: good tooling (including incremental compilation) or custom-tailored syntax?
Syntax is important, but obsession about syntax (to the point of rejecting hundreds of existing languages) is bikeshedding.
Basically none of the existing languages have the features that I need:
1) Compilation speed. V compiles 15 million lines of code per second. Only Go and Delphi are relatively fast.
2) Simplicity & maintainability. Only Go is simple. I made V even simpler and stricter.
3) No runtime/GC. I want the language to be close to metal so that it can be used to develop small and fast native apps, games, drivers, etc. Go's out.
4) Safety. Go has nil (runtime errors), no option types (verbose error checks and unhandled errors), data races, global variables.
5) Easy interop with C. Cgo ads a lot of overhead.
