le to goroutines running on other processors.
I would like to better understand how this works. What is it that makes this
‘flush out’ to happen? Is this a system call?

I do not think priority select is *necessary*, it could be a nice addition
if the performance does not change.

I think there I show it is possible to workaround that limitation using
standard Go tools. Of course, the code would be simple with priority
select, but also perhaps select would be

gonum is a very interesting project which plays in the same space as

Me too I have to add struct tags to over 300 objects, repeating the same

computer should do for me.
In the end I've used a tool that parses the .go files and adds the tags
