[Haskell-cafe] Status of ghcup?

[Todd Wilson]

Sigh. As a college educator who is trying to use Haskell in as many classes
as possible, I am still disheartened by how much effort is required by
students to get the toolchain and additional libraries installed and
working on their various platforms. I usually have to waste time during the
first two or three weeks of class (and this semester it has extended to
more than four) with students over this, whereas instead I should be able
to send out a link before my class begins and expect that almost all of
them will have everything installed on the first day. I know this topic has
been discussed here and elsewhere, and that there are efforts underway to
improve the situation, but I just want to make a plug again for easy
Haskell installation for beginners. Diversity in the ecosystem is great,
but for people trying to get started, there should be one simple and
surefire way to get up and running, with a clear path later for upgrading
the environment in any number of different directions.
