Ghci panics with type applications to unknown functions
I haven't investigated further, but I stumbled upon the following:
Prelude> :set -XTypeApplications
Prelude> :t nonexistant @[]
ghc: panic! (the 'impossible' happened)
(GHC version 8.0.2 for x86_64-unknown-linux):
initTc: unsolved constraints
WC {wc_insol =
[W] nonexistant_a2YB :: t_a2YA[tau:3] (CHoleCan: nonexistant)}
