Foo, Bar, Baz…: The Metasyntactic Variable and the Programming Language Hierarchy

This article argues that the English-language nonsense words “foo,” “bar,” “baz,” and others in a more or less standardized sequence of so-called metasyntactic variables commonly used in computer programming ought to be understood as meta-abstractive, re-representing a linguistically derived code’s abstraction of language and the abstraction of the programming language hierarchy itself, making it legible in a manner that rewards culturally oriented study: for example, of programming as a culture and of cultures of software development or engineering.
