Hi all,
I am one of the contributors on the Stack project:
https://github.com/commercialhaskell/stack
It is one the major build tools which the Haskell community relies on.
I am currently testing the waters to see if Stack might be a candidate
for a proposal on the 'Foundational Technology' path of the MOSS
programme.
I am not sure of the status of Haskell use at Mozilla. I can see a few
listed foundational projects rely on the Stack ecosystem. I'd love if
any Mozilla Haskell people could reach out to discuss!
Best,
Luke
