Question

Hi again folks Another question around mapping transformation of outputs to inputs How can I accomplish an `Output Format ` if my format string is not a string interpolation inline in code but instead a composite format string containing ` 0 ` placeholders that is fetched from an external source such as an environment variable

If there is just one `Input` I suppose I could call `String Format ` inside an ` Apply ` on that input

But in my case there are multiple `Input` that each correspond to a placeholder in the composite format string

Right the answer is effectively always ` Apply` And if you have multiple inputs ` All Apply ` Other things like `Output Format` are effectively all just sugar for common cases but if your case falls outside of those you want ` Apply` and maybe ` All`
