The first three drafts of my favourite test program (a program to drive servos to point a heliostat mirror at mirrorLattitude, mirrorLongitude, mirrorAltitude in altitude and azimuth to direct the reflected ray at targetLattitude, targetLongitude, targetAltitude) wouldn’t run.

It’s very rare for any AI to use real modules for the language (even when I say “please use library modules that exist in CPAN”) and they nearly never know how to reflect a ray
