- scheme/sort/* added by hand (for some reason it wasn't merged in)
- currently, some READ-PARAGRAPH tests don't pass: apparently,
due to some problems with the regexp library.
type->sexp was not capable of converting the variable type to a
sexp. This caused problems if the module system wanted to tell the
user that the types of exported bindings did not match:
config> (define-structure foo (export (bar :syntax)) (open scheme) (begin (define bar 1)))
; no values returned
config> ,user
> ,open foo
Error: exception
wrong-type-argument
(checked-record-ref '(variable #{Type :value #f #f}) '#{Record-type 14 meta-type} 1)
I've now extended TYPE->SEXP by a check for the variable type and let
it produce a list with 'VARIABLE as first and the actual type as
second element. Likewise, I extended SEXP->TYPE to produce a variable
type if 'VARIABEL is the first element of a list.
This seems to work but a second look by someone who really understands
the type system would be appreciated.
