Wow! The reader emits fake calls to unquote functions— allowing for custom syntax-quote-like macros if you don’t like the one built into the reader:

  • '~foo => (clojure.core/unquote foo)
  • '~@foo => (clojure.core/unquote-splicing foo)

Someone in 2008 wanted a syntax-quote without symbol resolution (i.e. quasi-quote) here, and Rich added the fake calls to allow it:

It looks like a canonical quasiquote was published four years later in 2012 (which I had starred and forgot about):
