I would rather go for something like:
StdForwardList{<element type>} with X elements:
2
3
1
similar to the way Julia Sets are printed. The [] syntax risks confusion with arrays.

For a forward list, printing the length will require iterating over the entire list, so I have omitted the number of elements and now gone for this:
StdForwardList{Int64}:
2
3
1
src/StdLib/StdList.jl
Outdated

Done, it is now displayed like this
StdList{Int64} with 3 elements:
2
3
1
src/StdLib/StdDeque.jl
Outdated

The push methods for StdDeque also need to return the container, as is done for the other types.

Added iterators for
StdDequeStdSetStdUnorderedSetStdMultisetStdUnorderedMultisetStdListStdForwardListBase code from #433
Also added pretty printing for
StdListandStdForwardList, since they do not have a parent Abstract Type in Julia
