My impression was a few (5 to 10?) years ago, MIT changed the intro class to Python and moved Scheme to be after Python. When I talked with Hal & Gerry at the time, they were OK with the change.

This 1986 taped class was a special one, I think for HP.

If you enable 'warning level for the 'optimizer logger, it will sometimes print helpful things like: optimizer: warning in: /path/to/file.rkt:338:3: in module: optimizer detects procedure incorrectly applied to 2 arguments: some-function. Is there some way to print these when using raco setup? Even better, is there some sort of treat-warnings-as-errors option?

Does setting PLTSTDERR='error warning@optimizer' work?
