It has to do with module boundaries and how syntax properties are preserved. https://groups.google.com/d/msg/racket-users/ZWjpz3kFmjo/SUXGVM3YEAAJ
It's been a while since I wrote this, but the work around I used was exporting the identifier that *expanded into code* that inserted the syntax property. This way, ths property doesn't need to be preserve, since it gets inserted every time it is used: > The workaround seems to be: if you want to stash an identifier in a > syntax-property, expand into syntax that attaches the syntax-property.
