A package will rejected if \dontrun is not needed and there are better 
ways to structure the examples. Frequently code such as Ivan's proposal

    (reticulate::py_module_available(...)) { ... }

is perferrable, so that the code runs if the requirements are fullfilled 
/ suggested packages are available.
