Minor fix to pretty-printing of linear types
As noticed in !4201 (comment 304421), the function ppr_arrow_chain
was not printing multiplicities of fields of a data constructor. Simple fix. The function isn't used much. Test haddockA035
covers the case when -XLinearTypes
is off.
Remove the Outputable
instance for HsScaled
- no longer used and could cover bugs like this one.
