Capture args from repeatable flags in Golang pflags package
How do I create a flag that can be used multiple times in a command using [the `pflag` package](https://github.com/spf13/pflag)? For example, let's say I wanted to select multiple fields and did not want to have to use comma-separation with a single flag, but instead something like follows:
cmd -f field1 -f field2 -f field3
I'd want to add each argument passed to an `-f` flag into a slice (or into a `map[string]struct{}`).
1. Is this already built into `pflag`?
2. How do I accomplish this?
