inline infix fun T.or(orBlock: () → T) = if (this == null) orBlock() else this

Support for Groovy style "Power Assertion" in Kotlin?

Does this seem like it could work for you? inline infix fun <T> T.or(orBlock: () -> T) = if (this == null) orBlock() else this Here’s an example: val a: String? = null val realA = a or { "b" // imagine we actually did work instead } println(realA) // prints out "b"
