Define auto indentation rules

[fredrik-bakke]

Defines rules for auto indenting common scenarios where the code must be indented to type check regardless. The only exception where the code doesn't strictly have to be indented is after a ⦃, but having this indentation rule makes it consistent with the behavior of ( and { and so on.

Can you resolve the conflicts?

Sure thing! Give me a second

Hold up a second, I think I spotted a mistake in one of the patterns.

[fredrik-bakke]

Fixed now :)
