No idea ;)

Yeah `convert` should just be for `String`. And totally SparseArrays.jl code can go in an extension. (There didn't used to be a loading time cost to SparseArrays)

Think of the sheer number of floating point operations happening in summing your 10_000 * 10_000 array. Theres a lot of room for error to creep in There is a...

But seems we don't actually use kahan summation, but pairwise. And not on a regular iteration: https://discourse.julialang.org/t/kahan-summation-in-sum/102723

For me it was a fraction of a percent, but still big. But its a real problem, thus all the algorithms to fix it. Try looking in Base for what...
