```sh
gleam add trim3
```
```gleam
import gleam/string
import gleam/list
import trim3
pub fn main() -> Nil {
let strip_chars =
string.to_graphemes(" \t\n") |> list.map(string.to_utf_codepoints)
// let trim = trim3.trim3_start(_, strip_chars)
// let trim = trim3.trim3_end(_, strip_chars)
let trim = trim3.trim3(_, strip_chars)
assert trim(" Silly\r\r\r ") == "Silly\r\r\r"
}
```

## Why?
I needed to trim many lines which only includes space, tab and line-feed. Gleam
string.trim (Erlang trim/1, trim/2) looks for 11 different characters and the
crlf pair. Cut time spent trimming lines in half. Not that I will ever ever
gain that back from doing this. Sunken cost!
And it should probably be a PR instead of a package. But hacks are afoot.
