If you want to peer into an alternative reality / funhouse mirror of programming terms, you should look at ALGOL 68. For instance, types are called "modes".

(There are also "incestuous unions", which is the actual term used in the spec.)

Huh - R has a concept of “mode” that overlaps and complements “type”… but then again R also a very funhouse mix of terminology.

From the docs, an incestuous union is the equivalent of a packed union in C? Well, you gotta be packing' to be incestuous :D
