Kevin I tested in my Win laptop with 0.3.11, 0.4.2, 0.4, 0.5+ also the same versions in julia box, and the output is deterministically sorted, It seems this has been the way it works for some time now, then I looked at the code and it’s indeed sorted (should have done that first! :P ):
- http://git.io/vEXL9 subtypes(m::Module, x::DataType) = sort(collect(_subtypes(m, x)), by=string) subtypes(x::DataType) = subtypes(Main, x) I would expect a very good reason in order to justify a change for this now.
