Just a heads up everyone. Gitlab appears down again. This seemed to have
happened around Sunday, 4AM UTC.
Everyone have a blissful Sunday!

Hi Alexis,
The following works and will have inferred type `Int`:
> bar = foo (\(HNil :: HList '[]) -> 42)
I'd really like it if we could write
> bar2 = foo (\(HNil @'[]) -> 42)
though, even if you write out the constructor type with explicit
constraints and forall's.
E.g. by using a -XTypeApp

But aliasing the promoted constructors via pattern synonyms, and using
those instead, appears

I can also help (~UTC+1), I've a long history and experience in
systems management and engineering.

Hi all,
Today I was writing some code that uses a GADT to represent
heterogeneous lists:
data HList as where
HNil :: HList '[]
HCons :: a -> HList as -> HList (a ': as)
This type is used to provide a generic way to manipulate n-ary
functions. Naturally, I have some functions
