Hello,
I'm making composite picts in my Scribble docs and am looking for a clean
way to keep references to sub-picts around for helper functions to draw
lines between. A struct with the `prop:pict-convertible` property would
suffice, but `raco setup` gives an error.
Given this struct definition:
(struct my-pict () #:property prop:pict-convertible (λ _ (circle 30)))
If I call its constructor from Scribble:
@my-pict[]
I get the error:
not valid in document body (need a pre-part for decode) in: #<my-pict>
Manually `pict-convert`ing can be painful. Is there an easier way?
Thanks!
Eric
