Re: Is set-environment-variable needed after all? Lassi Kortela 09 Dec 2019 10:38 UTC

One more use case: Common Lisp has an `ed` function that launches a text
editor. I have a pending SRFI that provides that for Scheme, and it'd be
nice to use (get-environment-variable "EDITOR") to figure out which
editor to use in a Unix terminal.
