Suppose I have Geo::GDAL::Layer::features. There may be millions of
features in one layer. If this method really returns all of them in a
list, it may take a while. Would scalar (Geo::GDAL::Layer::features)
then also take a while, or can I somehow detect that inside the method
(with wantarray) and call featureCount and return what it returns.. hmm,
maybe I can. And what if the user calls it like this:
Geo::GDAL::Layer::features->[34] to get just one feature?
I'm just trying to figure out what methods are needed:
feature
features
addFeature
featureCount
etc..
I've updated http://map.hut.fi/gdal-perl/Geo-GDAL.html but it's not
finished since it will contain _all_ classes and their methods.
