This issue is to document a likely problem with the LAPACK package module. With the addition of const qualifiers in generated C code, several package module extern functions broke due to implicitly passing an array const ref to a mutable C pointer formal. As LAPACK's interface and the file wrapping it are massive, it's infeasible to update every instance of this manually. I made a best attempt at it in the PR but it is likely there are instances of both 1) unnecessarily mutable refs and 2) const refs that need to be mutable.
