In studying the bt and the code, it seems like the problem is here, in
/home/christopher/.config/guix/current/share/guile/site/3.0/guix/scripts/deploy.scm
around line 176
```
(define (invoke-command store machine command)
"Invoke COMMAND, a list of strings, on MACHINE. Display its output (if any)
and its error code if it's non-zero. Return true if COMMAND succeeded, false
otherwise."
(define invocation
#~(begin
(use-modules (ice-9 match)
(ice-9 rdelim)
(srfi srfi-11))
```
For some reason the "#~" g-expression syntax is not being recognized here, as
far as I can tell without knowing much about g-expressions. I see that the
(guix gexp) module is being used, so I suppose it must have something to do
with the way the syntax is being used (misused?)
