Paul Graham called these "anaphoric" macros in On LISP.

  The "anaphora" in "anaphoric" typically refers to how it binds the variable "it" automatically, without having to specify the variable name. Since if-let and when-let require you to explicitly specify the variable name, I don't think most people would consider them anaphoric macros. https://en.wikipedia.org/wiki/Anaphoric_macro https://en.wikipedia.org/wiki/Anaphoric_macro If you want actual anaphoric macros in CL, here they are: https://www.common-lisp.net/project/anaphora/ https://www.common-lisp.net/project/anaphora/
