I’m still perplexed how cryptic the docs are. No info on return types. Also [this example](https://discourse.julialang.org/t/archgdal-jl-or-gdal-jl-not-sure-undesired-behaviour-when-reprojecting-coordinates-to-epsg-4326/59415) crashed with MethodError, couldn’t find how to call it on a vector.

```julia

cities2 = GDF.read("/tmp/cities.geojson")
sc = AG.importEPSG(4326)
tc = AG.importEPSG(3857)

AG.createcoordtrans(sc, tc) do transform
    AG.transform!.(cities2.geometry, transform)
end

```
