current max_docid_ can only increase, deleted doc still count and stop new doc being added.
vearch becomes unavailable. Is some way to solve this problem?

Instead of:

{
  Get {
    Things {
      Article {
        title
        url
        wordCount
        HasAuthors {
          ... on Author {
            name
          }
          ... on Publication {
            name
          }
        }
      }
    }
  }
}

Use

{
  Get {
    Things {
      Article {
        title
        url
        

Rawgit seems to be shutting down, as can be seen when you click the "source" button in the documentation. Maybe we could move it under unicredit.github.io/neo/?

In Numeric.Matrix: perspective and orthogonal currently follow OpenGL conventions. They require negative near and far values, otherwise they produce bogus Z values and messed up signs. The haddock comment on perspective states "Near plane clipping distance (always positive)" which is wrong. I suppose the OpenGL convention sees them as z-coordinates of the planes in screen space instead o
