"panic: Enum" while processing notcurses.yml

Hey there! I'm the author of Notcurses, and I'm considering use of c-for-go to generate our Go bindings. I've created the following simple notcurses.yml:

[schwarzgerat](0) $ cat notcurses.yml 
# run ala "c-for-go -ccincl notcurses.yml"
---
GENERATOR:
  PackageName: notcurses
  PackageDescription: "Go bindings for Notcurses"
  PackageLicense: "Apache-2.0"
  Includes:
    - notcurses/notcurses.h

PARSER:
  # use -cincl when running c-for-go
  IncludePaths: ["/usr/include"]
  SourcesPaths: ["notcurses/notcurses.h"]

TRANSLATOR:
  Rules:
    global:
      - {action: accept}
      - {load: snakecase}
[schwarzgerat](0) $

and am running this on my installed 1.7.6 notcurses/notcurses.h. I get the following panic:

[schwarzgerat](0) $ ~/src/c-for-go/c-for-go -ccincl notcurses.yml

(btw, is that Braille character intended?)

anyway, I can dig into this, but I thought perhaps you might know what's up immediately. Feel free to request whatever in the term of debugging/verbose runs, etc.
