I was hoping this would work, but get all sorts of weird stuff.

```julia
using ZipFile
z = ZipFile.Reader(archive_filepath)
files = z.files
iter = (f -> f.name => f for f in files) # which is Base.Generator{Vector{ZipFile.ReadableFile},
d_by_name = Dict(iter)

```

was hoping for  
Dict{String,ZipFile.ReadableFile}

getting error:  
`LoadError: ArgumentError: Dict(kv): kv needs to be an iterator of tuples or pairs`

I am totally lost…

ZipFile documentation seems very incomplete…

Looks like I was over-wrapping the iterator. Dict() seems specialized.  
This works

```julia
using ZipFile
z = ZipFile.Reader(archive_filepath)
z_by_name = Dict( f.name => f for f in z.files)

```
