“Python's batteries are leaking”

Oof, I wasted a good hour+ trying to convert from one to the other. Maybe there's an easy way to do this, but not many people on IRC knew (or were available at the time).

    use std::iter::FromIterator;
    BTreeMap::from_iter(hash_map.into_iter())

Or .into_iter().collect(), I believe. No import needed.

Assuming the keys are Hash + Ord, wouldn't that just be:

  for (k,v) in &src
    { dst.insert(k,v); }

?

Yes, that's what I ended up doing, but the error confused me and I ended up looking for a less hacky way for more than an hour until I said "fuck it" and just did that.
