I don’t understand why people try to unit test handlers. Use integration tests for this and the real services you depend on, use unit tests to test functions and business logic, not glue code like handlers. If you build a vast complex web of mocks attempting to reproduce behaviour you’ll only test the happy path and failures you can think of. It’s lots of work for no benefit.
This is interesting, but seems a little unnecessarily complex in places. Not sure they need to stray so far from Go. You can pretty much do exactly the same thing in golang just with a check(err) function which panics instead (tried to paste this into this comment as code but the formatting wasn't so good (no newlines)).
which is pretty superfluous I agree and nice to ditch (but could be handled by a preprocessor for scripts). And a line of error handling, which I much prefer explicit in pure go like this:
f, err := os.Create("hello.txt") check(err)
Now a check function that just panics is only useful on short scripts, but it would seem easier to have explicit error handling than produce an entire new dialect for this.
Not sure how profitable comparisons of languages like this are, but it is a choice we all face. Go mostly leaves things out (except perhaps a better concurrency story than python), so in a feature by feature comparison, it's going to look less impressive at first.
It's certainly less easy to get up to speed in if you're learning programming for the first time, and in different domains it has completely different strengths (for example python has far more mature science and data analysis libraries, because lots of people are using it for that).
This looks amazing, I really like that you have posted some content as well, so that people can learn about this stuff. Are there any talks on this subject we can look at?
The biggest problem I had was getting my head around pointers vs method receivers and which to use (I ended up using pointers for almost everything). Also was tripped up by map key iteration order changing. Otherwise it's been pretty plain sailing learning go compared to some other languages.
Nice. Interesting to see people exploring building a new container host rather than just using docker.
Didn't know reddit used Go, everyone seems to now!

Still broken for me.

Raytracers! It's not as complex as you might think to write one of these so a perfect way to get to know the language.
