TODO: Mention build speed impact.
<p> <!-- https://github.com/golang/go/issues/49569 -->
Because of changes in the compiler related to supporting generics, the
Go 1.18 compile speed can be roughly 15% slower than the Go 1.17 compile speed.
The execution time of the compiled code is not affected. We
intend to improve the speed of the compiler in Go 1.19.
