When you open this file in Emacs≥28, the modeline will have an orange
"/d" which is meant to warn you that something's amiss.
Click on it, and your problem will be solved :-)

Your code ends up (via the `sint` of `bindat-type`) relying on the
`lexical-binding` dialect of ELisp, which is enabled by default in
`ielm` but not in your file.
