I mean, not using the Haskell Platform. I think if you're an
experienced developer you'd package just the things your project
needs, instead of using the whole Haskell Platform. I don't think the
Haskell Platform is the bare minimum.

True, that's pretty small.

That's pretty good! Encouraging if I write an end-user desktop
application and want to embed Haskell as a scripting language.
