How is there no common String.format yet? 😞

Not enough votes I guess. https://youtrack.jetbrains.com/issue/KT-4859

The main reason is that

String.format

is localized and internationalization is a pain and difficult to do right. It’s not something the dev team can confidently implement in common code yet. Plus, it’s much less needed when you have string interpolation available

Thank you. I get the localization issues. For now I just needed a 0 leading precision flag. I will roll my own for now.
