keys(ENV) just spits out all the keys as one big object. Things like keys(ENV)[0] don't work either. Additionally, I can't do things like filter with an EnvHash to search for environment variables that may or may not have been set.

KeyIterator is not going to be any more numerically-indexable than dictionaries are.

filter could work of course; it just doesn't know what kind of object to return. I suppose it should be a Dict{ByteString,ByteString}.
