17:27 <afm-victoria> I am reading The Little Learner and want to use the package plot to look at some of the functions in the book (e.g., plane). But it looks as though the plotting functions in plot need arguments of type 'number' and have no clue with type 'scalar'. I looked at the docs for 'malt', the language for the book and see no conversion functions. Any suggestions?

17:36 <afm-victoria> Specifically, operations like `(- 0 pi)` result in a value for which `scalar?` returns #t but `number?` returns #f.

22:00 <kengruven> according to the def in https://github.com/themetaschemer/malt/blob/main/learner/tensors/0-duals.rkt it looks like you've got a dual and need to deref it with ρ

22:00 <kengruven> darn, too late
