slice

To run the generic version:

$ go run slice.go -bool=true
$ go run slice.go -int=5
$ go run slice.go -string=foo

To generate the string version:

$ gengen -o slice_string github.com/joeshaw/gengen/examples/slice string

To run the string version:

$ go run slice_string/slice.go -string=foo

If you attempt to pass -int or -bool to the string version, it will panic because the Contains() function is strictly defined to take a string argument.
