Thank you!

That makes sense.

Thanks!

I'm still reproducing the check-declare bug on my machine. It appears
that binding `enable-local-variables' to nil around the call to
`hack-local-variables' means that `read-symbol-shorthands' is not set.
Can we bind `enable-local-variables' to `:safe' instead?

(let (
      ;; (enable-local-variables t)   ; works
      ;; (enable-local-variables)     ; doesn't work
      (enable-local-variables :safe)  ; works
      )
  (with-temp-buffer
    (insert-file-contents "~/.local/src/hyperdrive.el/hyperdrive-lib.el")
    (hack-local-variables)
    read-symbol-shorthands))

See attached patch.

There's no way to hack just a single file- or dir-local variable, right?

Thank you!
