> Spack cons. Not as well-suited for general-purpose development

While I would not use Spack (or any package manager) to drive the usual hack-build-test development loop, Spack does provide at least two mechanisms to support that kind of general-purpose development activity: "environments" and "views".

Given the list of build systems includes SCons, I'd expect to see waf (waf.io) here.

There is also `spack develop`, on which people are building hack/build/test loops. You can `spack develop` any package in spack, and easily build with a modified version of something.
