Adding a '(provide type)' in expander.rkt (where 'line' is defined) gets me
past this error. Strangely, providing 'compare' or 'offset' doesn't seem to
be necessary. I'm interested in any theories as to why this might be the
case.
Thanks for your help.

The error
line: bad syntax
(line (offset 0) (type (string8 "string")) (test (strtest "MZ")))
means that the macro `line` doesn't have a clause that matches the input.
How is line defined?

I'm bumbling through my first attempts at creating a language in Racket and
am currently stuck debugging an error in expansion. I have a macro in my
expander that works fine until I try to run the language.
Here's what the macro stepper in DrRacket gives me:
