Comment (by ncohen):
> Are we sure that we actually ''want'' to do this?
If you oppose the changes involving `Maple/Matlab` and others then I do
not mind removing them for you. We can keep Gurobi and CPLEX for they are
only used by Sage if the user explicitly linked them with it.
> 1. Never use `except:`. Use `except Exception:` or some other specific
exception class.
I thought that here it was pretty safe: I do not want this test to ever
break, and if there is something wrong with the mathematica/maple/...
interface, then other doctests will have to report it.
> 2. Code structure: can we please move all this detect-optional-packages
code to a separate function?
I will add a commit.
> 3. Performance: how much time does it take to run all those tests?
Almost nothing, give it a try. That's clearly negligible against the time
it takes to run the `sage -b` part of `sage -btp`.
> Note that #13540 has a system for "lazy" checking of optional
dependencies
I do not see a need for that given the time it takes to run those tests.
Especially, if you want the maple/matlab/others to be removed from the
list.
