Just sending "true" as a signal is a convention, but some people prefer something like http://play.golang.org/p/oXapo7R4RX http://play.golang.org/p/oXapo7R4RX

- frou_dh 13y agoCool, I like that. In some ways, it would be nice if there were a friendly alias for struct{} as part of the language, but I suppose it's hard to come up with a good general name for that.
- exch 13y agoI'll add that the reason for using `struct{}` over `bool`, is that an empty struct occupies 0 bytes, whereas a boolean occupies 1.
