Tiny Gleam caching Context for your functions

```sh

gleam add functx

```

```gleam

import functx.{type Ctx}

fn nums(ctx: Ctx(Int)) {

  // this function called only once during context

  let #(n, _) = ctx

  #([1, 2, 3, 4, 5, 6, 7, 8, 9, n], ctx)

}

fn nums_as_string(ctx) {

  use ns, ctx <- functx.call(ctx, nums)

  let resp =

    ns

    |> list.map(fn(n) { n |> int.to_string })

    |> string.join(",")

  #(resp, ctx)

}

fn nums_to_sum(ctx) {

  use ns, ctx <- functx.call(ctx, nums)

  let resp = {

    use acc, n <- list.fold(ns, 0)

    acc + n

  }

  #(resp, ctx)

}

fn nums_summary(ctx) {

  use ns_str, ctx <- functx.call(ctx, nums_as_string)

  use ns_sum, ctx <- functx.call(ctx, nums_to_sum)

  let resp = "Nums: " <> ns_str <> " Sum: " <> ns_sum |> int.to_string

  #(resp, ctx)

}

pub fn main() {

  let resp =

    10

    |> functx.make_ctx

    |> nums_summary

  resp.0 // Nums: 1,2,3,4,5,6,7,8,9,10 Sum: 55

}

```
