is there a better kotlin form of this java-ish code? operations is a mutablemap

val opList = operations.computeIfAbsent(
    basePath
) { key: String? -> ArrayList() }

[Casey Brooks]

map.getOrPut(key) { value } is the Kotlin version of that function, which is available on non-JVM targets, too (unlike computeIfAbsent)

[ephemient]

note that getOrPut has different locking guarantees than computeIfAbsent, if that matters to you
