Or [1]. The tl;dr: add "where rnf x = seq x ()" to the instance to get
the old behavior.

I made an unofficial OS X build again [0]. I'd be happy to offer my

I think this proposal is currently underspecified. For example, it's
not clear to me what the semantics of a FilePath are. I have the
feeling that `toFilePah` should return a Maybe, for example, but it's
hard to say without knowing what it's converting to, exactly.
I also worry about the immense b
've had, and those have already caused a lot of grumbling.
But the only way to be sure is to run the builds on hackage (or
stackage, but that's a smaller sample size).

I've found what I believe to be a regression in GHC 8 rc2 [1], and the
wiki says to yell if I want to bring it to the attention of GHC
developers. So this is me yelling, I guess :) I'm not sure if this bug
is important enough to be included, but I think it would be good for
someone to look at it an

Others have already commented on many aspects of this discussion, but
I just wanted to mention that cabal has an '--allow-newer' flag to
disregard these constraints, so '--allow-newer=base' would allow you
to try and compile this package with GHC 8. Since GHC 8 is very recent
though and base 4.3 is
What do you expect will be the distribution of 'soft' and 'hard' upper
bounds? In my experience, all upper bounds currently are 'soft' upper
bounds. They might become 'hard' upper bounds for a short while after
e.g. a GHC release, but in general, if a package maintainer knows that
a package fails t
s fixed a hard upper bound is required. Likewise for

I noticed this as well, since my work VPN does fairly strict certificate
checking and didn't allow me to connect to any haskell.org urls due to this.
I'm not sure about the right list, I've added ad...@haskell.org to the CC
list.
