maybe add
(define (make-foo-x a b) (make-foo a b))
then call make-foo-x (or reverse names)

Good day guile-users,
I am having a struggle with SRFI-9 records. They look very
convenient, so i'd like to use them in my Guile scripts. However, i'm
not sure how to correctly construct them from C-land. I have
something like the following:
```
(define-record-type <foo>
(make-foo a b)
foo?
(a foo-a)
(b foo-b))
```
In Guile land, that works great. Now, i want to create a foo in C and
pass it to a function in the Guile script. I do something like the
following:
```
scm_c_primitive_load("foo.scm");
scm_call_5(scm_variable_ref(scm_c_lookup("make-foo")),
scm_from_utf8_string("blah"),
scm_from_int32(Int32(42)))
```
However, this results in an error:
guile: uncaught exception:
Wrong type to apply: #<syntax-transformer make-foo>
I've tried with and without (define-module foo) at the top of the
file, that doesn't seem to make a difference. I've been able to work
around the issue by defining a wrapper (define (foo-prime a b)
(make-foo a b)) and using that in C as shown above, but that feels
ugly. I'm probably missing something obvious, but trawling the
mailing list didn't turn up anything i could understand.
Does anyone see what i'm doing wrong, or can i simply not use SRFI-9
records in this way?
Thanks, 🙌
p.
