Re: limits for (export ...)

I decided to generate a file with ~100 definitions.

; manysyms.scm
(define-module (manysyms)
  #:export (sym0 sym1 ... sym101))

(define sym0 'sym0)
(define sym1 'sym1)
...
(define sym101 'sym101)

; test.scm
(use-modules (manysyms))
(write (list sym0 sym1 ... sym101))

And when I ran test.scm I got the expected output, so I'm not sure there
is.

Although, and I don't think this is related to your issue, when
trying out the (list sym0 ...) from the repl, I did get an error

scheme@(guile−user)> (list sym0 sym1 ... sym100 sym101)
;;; <stdin>:3:0: warning: possibly unbound variable `sy'
;;; <stdin>:3:0: warning: possibly unbound variable `m85'
<unnamed port>:3:0: In procedure #<procedure a08bf50 at <current input>:3:0 ()>:
<unnamed port>:3:0: In procedure module−lookup: Unbound variable: sy

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile−user) [1]> ,q

But further exploration shows that all the symbols are in fact bound,
and this error only seems to occur if there is no line break at some
point after sym8 and before sym85. Presumably, I'm running up against
some reader limit there.
