I had the exact same issue a while ago with the docs with Julia 10.4. It turned out that the dependency (FerriteMeshParser) was only partially downloaded. Found this by manually inspecting the depot folder (.julia/package/FerriteMeshParser). I could come up with a reproducer and eventually forgot about it.

Perhaps? (Not the best error message in that case, trying to Pkg.update gave better error)

- git-tree-sha1 = "5c0ffe1dff8cb7112de075f1b1cb32191675fcba"

Ah, thanks, that was not intended to commit. Weird that Pkg didn't complain about that indeed.

[KnutAM]

LGTM, just some minor suggestions.

Are there any measureable improvements when not creating many Vectors{Vectors} here as well? In that case, perhaps a small comment would be nice for users to understand why we use VectorOfArrays?

[KnutAM]

The above needs to reflect that a tuple is used I think?
