Also 'cgo' comments which are fairly old. See: https://golang.org/cmd/cgo/ https://golang.org/cmd/cgo/ For an example of what this looks like in actual use, see the very popular go-sqlite3 library: https://github.com/mattn/go-sqlite3/blob/dee1a37fe11067e97971fac64fa5bff4ef0934f4/sqlite3.go#L8 https://github.com/mattn/go-sqlite3/blob/dee1a37fe11067e9797... I personally think that large block-comments of code that actually do something, but only if above a certain import really strange and unexpected; it means re-ordering imports can break things, changing around spacing can break things, and tons of other things.
