Julia: Better printing of `zip` output

[musm]

The printing of zip is quite unreadable for even simple arguments:

julia> zip((:a,:b,:c), (1,2,3))
Base.Iterators.Zip{Tuple{Tuple{Symbol,Symbol,Symbol},Tuple{Int64,Int64,Int64}}}(((:a, : :c), (1, 2, 3)))

Can we include better printing of zip outputs so that for interactive sessions, it's easier to scan?

[StefanKarpinski]

Sure, should be easy enough. My suggestion is to print it as it's called, i.e. just

zip((:a, :b, :c), (1, 2, 3))

[musm]

Sounds good to me. Do we do that for any other types ?

[vtjnash]

Sometimes, c.f. showarg & such

[StefanKarpinski]

Also typeof(+) and so on.

Would it be good to do this with all functions from Base.Iterators? Or at least the ones that are imported into Base?

[nalimilan]

skipmissing would probably benefit from this too.

Relevant issue here regarding best practices for the two argument show method.
