Subject: Meaning of <=> in the context of procedures
Date: Wed, 2 Jun 2021 10:06:08 -0400	[thread overview]
Message-ID: <CAOcxjM7xhWKo0z6XMoiFEJLXffBhTDi7oArh=pdNg4-Fq3znSA@mail.gmail.com> (raw)

Hi,
What does <=> mean/do?
It can be found in guile-json in the (json record) module, line 33:

33 #:export (<=> define-json-mapping define-json-type))

Not mentioned in the entire Guile manual. Happens to be defined on line 36
of the module:

36  (define <=> '<=>)

I didn't find that very helpful :)
Thanks
Mortimer
