I'm strongly considering taking this opportunity to improve the API. The change is backward-incompatible, however, so I need input from those of you who use Plot a lot. In particular, recent experience with Pict3D makes it clear that the type of the `plot` function shouldn't be this: (-> (Treeof (U nonrenderer renderer2d)) ... (U Void (Instance Snip%))) but should be this instead: (-> (Treeof (U nonrenderer renderer2d)) ... Plot) where a `Plot` instance is a value that can be queried for its properties (such as the legend, plot bounds, ticks, etc.) and just happens to print in DrRacket as an interactive snip. The type of `plot3d` would be changed to return `Plot3D` instances. Casual uses wouldn't see any change at all. However, functions that receive or return plots, *which also put contracts on plots*, would have to change to use `plot?` instead of (is-a?/c snip%), or use (require plot/snip), a new compatibility module, instead of (require plot). How many programs of yours would this change break? Any objections? Any suggestions?
