You can trivially sidestep this with a main shell function called at the end of your script. https://github.com/terrastruct/d2/blob/729b12685af79bbdaf4b3...

Kinda! The author of the script can trivially avoid the problem. The person pasting "curl ... | bash" into their terminal needs to rely on them having done so, which (last I looked) they too often haven't.
