> What an amazing tool that can completely change function names when it converts from C to Go.
How can one read the code of the benchmark, then switch into virulent sarcasm mode without trying to understand the code? And seeing "+1" comments without any effort to understand is also disheartening.
The blog post had a link about the Go helper functions the author used. It lands on https://github.com/akhenakh/goh3/blob/main/h3.go This shows that the `FromGeo()` function used by the Go benchmark is a helper that calls transpiled functions. The benchmark code itself was of course not transpiled, so the sarcasm was unneeded and wrong.
If anyone wants to dig in deeper, the C function `latLngToCell()` calls 2 functions, see https://github.com/uber/h3/blob/master/src/h3lib/lib/h3Index...
The Go function `XgeoToH3()` allocates a TLS then calls the

same functions, see https://github.com/akhenakh/goh3/blob/main/ch3/a_linux_amd64...
The C and Go code may not be strictly identical, but they seem pretty close. Enough to suppose the blog post was sincere.
I believe the right thing to do is to ask the author why they used a custom rewrite of `latLngToCell()` in Go instead of calling the transpiled function.
