> it dynamically links against 4 libraries (on OS X, anyway) while the Go version links against zero.

And how exactly does that work out on platforms that don't have stable syscalls?

View on HN

On Mac, Go breaks the rules and hardcodes syscall numbers anyway.

On Windows, Go dynamically links to kernel32.dll and friends.

So in theory Go programs can't be considered reliable across multiple versions of macOS without recompilation then?

It only matters if it also happens in practice.

It does happen in practice:

All forwards-compatibility issues were only "theoretical" issues that didn't "matter in practice" until a new release of the platform came out and suddenly they did.
