Re: Writing on Guile optimization: what are anon #x... functions?

Hi Skyler,

This made me grep through Guile sources. I found this function:

(define (addr->printable addr pdi)
  (or (and=> (and=> pdi program-debug-info-name) symbol->string)
      (and=> (primitive-code-name addr) symbol->string)
      (string-append "anon #x" (number->string addr 16))))

Seems like any function that's neither named in debug info nor a
built-in one is assigned the anon label. So these might be C functions
indeed.

I'm on Guile 3.0.9, so now I'm confused too!
