Cannot build GHC using the Newcomers guide

[Phyx]

Can I ask a silly question. I can't seem to find where stack is recommended
for ghc development on the newcomers page, but why is it? I don't want to
start another flame war but I can't imagine any scenario where this is
useful. As far as I understand the whole benefit of stack is the curated
packages.

Which are moot here since almost everything you need is in the tree aside
from Happy and Alex. Seems to me this is just overcomplicating a very
simple process.

Not to mention if you have to go through stack - - exec etc all for
interactions with the build artifacts it would get old quickly. Also it
doesn't seem reliable especially if stack is modifying the environment and
or flags passed to the compiler.

Let me reiterate, I have nothing against stack, I just don't see the
benefits here. Ideally you'd want your environment as simple and vanilla as
possible and *totally* in your control IMHO.

What am I missing here?

Thanks,
Tamar
