New post: the Go `select` statement
It's really two features:
- the compiler rewrites empty, single-case, and case+default selects away
- only the general case calls `runtime.selectgo`

In the previous article we walked through slices, maps, and channels, and how each of them is structured under the hood. Out of those three, channels are probably the most involved one in terms of how you actually use them โ and thereโs one language construct that really stands out when working with channels: the select statement. Thatโs what weโre going to be talking about in this post. And maybe Iโm cheating a little here, because this article isnโt strictly about the runtime โ select falls in between the runtime and the compiler โ but thatโs exactly what makes it an interesting corner of Go: it looks like a switch, behaves like a switch, and yet underneath itโs a coordinated dance between the compiler and the runtime.
Saturday Go deep dive: the `select` statement
It looks like a switch, but it's really two features in one: the compiler rewrites the easy shapes away, and the runtime handles the rest in a single function called `selectgo`.
I'll explain it on my Monday's blog post!
