That's a good remark. Alas, that will be hard to implement. In fact, I wouldn't want to hide those functions, rather give enough information to the compiler such that it can generate such code so that the user can decide in the user interface (HyperDoc, for example) whether s/he wants to see all functions or only the the non-superfluous functions. Then there is another problem. If we have 3 structures A < B < C (the bigger the more specialized) and function a from A is made superfluous by b from B, and further b is made superfluous by c from C, then the user interface should probably show that a is made superfluous by c. And we should perhaps show superfluous functions in a different colour, so that the important functions are easier to spot. Currently I would have to do that colouring by hand. Maybe the compiler can at least do something for a case like this, i.e., types and arguments agree. foo: X -> Y bar: X -> Y bar(x: X): Y == foo x Then bar could be tagged as "superfluous function". I don't know whether that covers already more than 70% of all the cases. Ralf -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
