undefined: http:MethodOptions

In the last month (probably with the most recent commits):

$ go get github.com/rs/cors
# github.com/rs/cors
/opt/go/src/github.com/rs/cors/cors.go:185: undefined: http.MethodOptions
/opt/go/src/github.com/rs/cors/cors.go:207: undefined: http.MethodOptions
/opt/go/src/github.com/rs/cors/cors.go:218: undefined: http.MethodOptions
/opt/go/src/github.com/rs/cors/cors.go:242: undefined: http.MethodOptions
/opt/go/src/github.com/rs/cors/cors.go:300: undefined: http.MethodOptions
/opt/go/src/github.com/rs/cors/cors.go:376: undefined: http.MethodOptions

It looks that it now requires go 1.6?

$ go version
go version go1.5 linux/amd64

I'm only testing back to go 1.8. I guess those constants were introduced in later versions.

I think it was introduced in go 1.6 (don't know go does a poor job of documenting earlier versions). In any case, this happened on my vagrant/chef instance which was using the default supermarket install (go version 1.5). I've since changed it to the version I'm using in production.

Might want to document this somewhere in the readme. In any case, I'm closing this issue.
