Right now if a query fails no descriptive information is provided.

An error type with some helpful information should be provided instead.

Sometimes it's desirable to find entities that may or may not have a component. An Optional query parameter could be used to make such queries.

Other frameworks just use the standard Option to represent the same thing, is that better?

Is there a way to get the Entity that a component belongs to? To for example, check the ID on it?

Sometimes it's beneficial to reserve space in archetypes before a bunch of archetypes are allocated. A call should be added to World that accepts a bundle of components and reserves space for them.

Iterators have many potential sources of unnecessary branching.

kudos is presently about the same speed as hecs and half the speed of legion.

Some care would be needed, but plain iteration speeds should be possible to bring to nearly the speed of legion.

Presently there are no tests. Tests should be added for major core features to protect against regressions.

Sometimes it's desirable to find entities that do not have a certain component. A Query parameter type should be added to accommodate that.

A survey of other Rust ECSs should be done to see if there are better ideas for a name than Without.

I don't know if this is already in, but I looked around and didn't find it. So, I was wondering if there was a way (or if it could be added) that you could do a query for an entity by it's ID? Like being able to do:
for (component1, component2) in world.query_for_entity(id) {
}
or:
let entity = world.find_entity_by_id(id);
:)

Love this crate! I've been using HECS for a while, and it's just a bit bloated and overcomplicated in parts. This one is just like a simplified version of HECS, and I love it! Great work! Love the Greek Mythology references in the example :)

Should it possible to iterate over empty entities? Should they be removed?

Some testing for bugs is needed here and an approach needs to be decided upon.
