The problem is that people will use the simpler function without
wondering and get bad performa
There is a discussion on this here:
https://github.com/JuliaLang/julia/pull/10963
(but I am still not getting the point)
Ok I just found a pull request that does just that.

That was clear from the usage of Val, but I am still not really getting it.

I also like (and use) dispatch on values, using the Val{:symbol}
construction, but when I can I always hide it from the "user" even (when
important for performance). Personally, I think
chol(A, Val{:L})
is ugly and also confusing for novices.
I am wondering: Why is it necessary to use disp
Try chol(B, Val{:L}) and chol(B, Val{:U})
