Too bad Apache Groovy itself didn't remain popular after popularizing the name "it" for the much older idea of contextually-defined pronouns in programming languages. Using the names of pronouns in English (like "this" and "it") is easier for an English-speaking programmer to understand than symbols like "$1" or "_". But because of Groovy's bad project management, another programming language (Kotlin) is becoming widely known for introducing the "it" name.
