For those who may come after me: if ./hadrian/ghci barfs with a Binary
runGet issue, the build tree that needs to be deleted is
`.hadrian_ghci`, not
? Not sure.
Anyway, if HLS behaves strangely, try deleting its build root.

Brilliant! Definitely working much better!
And @Sebastian I start to see the productivity gains. Remove all
redundant imports with one click!

The Binary runGet issue usually means that your build tree is out of date.
It's probably worth deleting and building from scratch again.

machine for months, and have
ys already.

Richard, this suggestion has been so useful that I would like to
follow it up.
I'm about to change a type definition. This change may wreak havoc in
many parts of GHC, and this is exactly what I want: I'm looking for
type-error messages that will tell me
