Today's AOC inspired idea for a utility function:

fun String.popSuffix(suffix: String) = if (endsWith(suffix)) removeSuffix(suffix) else null

[ephemient]

yeah, Rust's fn strip_suffix() ->Option<&str> returns None if it wasn't found, which is handy

[ephemient]

I wish it would at least let us provide a fallback value, like fun String.substringBefore(delimiter: Char, missingDelimiterValue: String): String does

Right

might not be a bad idea to suggest, I even think popSuffix is a decent, distinct name for it
