... all good points, and the implementation of Wisp is tiny anyway. For
an additional reason: Wisp is a SRFI (Scheme Requests for
Implementation) and Guile is a Scheme implementation.

From some conversations elsewhere, I got the impression that
(use-modules (foo))
will search for foo.scm and not in foo.w. I think you'll need to tweak
the loading mechanism to also look for foo.w instead of only foo.scm, if
not done already.
Also, I think that when foo.go exists, but foo.scm doesn't, then Guile
refuses to load foo.scm, though I'm less sure of that. If this is the
case, I propose removing the requirement that the source code is
available, or alternatively keep the 'source code available' requirement
and also accept 'foo.w', if not done already.

* Why avoid fluids?
* Assuming for sake of argument that fluids are to be avoided,
what is the point of setting the locale to something supporting
Unicode?
As-is, it now becomes impossible to use 'gettext' to translate software
to non-English locales when the software imports (language wisp), which
seems unfortunate to me. If you elaborate on what your goal here is,
maybe I have an alternative solution.
> + ;; allow using "# foo" as #(foo).

That's a rather Wisp-specific extension, but it appears you are
extending things globally. Instead, I propose extending it temporarily,
with the undocumented '%read-hash-procedures' fluid.

I think the convention is ';;', OTOH there exist multiple conventions.
+(define (wisp-scheme-replace-inline-colons lines)
+ "Replace inline colons by opening parens which close at the
end of the line"
Too much space; convention is two spaces.
(Similar styles issues in other places.)
"guix style" might be useful.

There is a risk of collision -- e.g., suppose that someone translates
your implementation of Wisp into Wisp. I imagine there might be a risk
of misinterpreting the 'REPR-QUOTE-...' in
wisp-replace-parent-quotation-repr, though I haven't tried it out.
As such, assuming this actually works, I propose using uninterned
symbols instead, e.g.:
(define repr-dot (make-symbol "REPR-DOT")).
If this change is done, you might need to replace
+ ;; literal array as start of a line: # (a b) c -> (#(a b) c)
+ ((#\# a ...)
+ (with-input-from-string ;; hack to defer to read
+ (string-append "#"
+ (with-output-to-string
+ (λ ()
+ (write (map
wisp-replace-paren-quotation-repr a)
+ (current-output-port)))))
+ read))
(unverified -- I think removing this is unneeded but I don't understand
this REPR-... stuff well enough).
Also, I wonder if you could just do something like
(apply vector (map wisp-replace-paren-quotation-repr a))
instead of this 'hack to defer to read' thing. This seems simpler to me
and equivalent.
(AFAIK, these REPR-... symbols are never written to a port or turned
into syntax, so I think that uninterned symbols would work here.)
(Aside from the REPR-... thing, I'm assuming (language wisp) is alright
-- the SRFI is in 'final' status and it has been stable for years now,
after all.)
Greetings,
Maxime
