I want to delete certain elements of an array at a given index, the deleteat! function seems like the best option but it is giving me an error message - deleteat! not defined.
For example I would've thought calling deleteat!([1,2,3],2) would return [1,3]. I'm using the current release v0.2.1, should deletat! be in the standard library of this release or is it only available in the v0.3 prerelease?
