It's a feature for sure. The article was a refreshing read too! Of course, hiding and abstracting away much of what is available in C, will have issues when you have special needs. But it beats "make configure" any day, and works well when you just need something with decent speed and memory footprint to get the job done.

I'm enjoying all of what you mentioned above, and dislike languages that are more C/C++ like now, as you often get "un-bit" by these snags using Go. However, Go has some snags on its own (hello slices!), so it's good to make sure one learns the fundamentals and what works well. A bit sad when repos import hundreds of other packages, I just turn away from such offers. It's been the state of IT for past 20 years that everything is essentially garbage. This is nothing new, and one just need to pick one's poison as you go along.

Nothing is ever simple either. All the "better solutions" in Rust, is sure to need refactoring and updates, while Go-code can mostly continue to run as-is. That's a good aim for its niche. Though, we all know the underlying platforms are very diverse, complex and come with snags of their own. I don't think the aim of Go is to tackle them all like "make configure" attempt to though.

I'll be happy to learn Rust for some herculean effort sometime.

Thanks for your comment

Picking up on one of your snags, Go's slices will "click" for you once you start thinking of it as a pointer and a length (and a capacity), but nothing more.

Realize it's just a C struct like this, passed by value:

  struct intSlice {
      int* addr;
      int len;
      int cap;
  };

The memory at addr is not owned by the slice. All the slice operations are simply notation for manipulating the struct. Go's garbage collection makes the whole thing work brilliantly

This can be confusing if you're used to std::vector (which owns the memory) or python's slices. Go's slices are a shallow pointer/length system exactly like is used in C all the time. For example:

  void sort(int* addr, int len);

becomes

  func sort(a []int)

A Go slice is just a pointer/length, with terse notation

For me I just use what's available and do not go into too much detail beyond what I need. However, slices can be confusing at first, and your above example could help think of them the right way. Although, until you get "bit", you might not deduct the consequences of slices right away. Especially when accustomed to other languages.

The latest thing that made me go "hmm" last time, was this one (I didn't get "bit", just went "hmm" reading it):

https://play.golang.org/p/2bTvXr6WLNN

  package main
  
  import (
   "fmt"
  )
  
  func main() {
   b := []byte{'g', 'o', 'l', 'a', 'n', 'g'}
   fmt.Println(string(b[1:4]))
   // Output:
   // ola
  }

I'm sure everyone expected this output when using b[1:4], right? All languages do these things a bit differently, so is why I always forget the detailed syntax required. I'm sure there's a valid pragmatic explanation and there's lots of ways to do this (ie. allow negative values etc.). Just a thing that while speedtyping, one could easily miss this little detail.

This one is a good intro, but doesn't explain this I believe:
