In errors like `value is an integer while a list was expected`, the message now
|
|
includes the failing value.
|
|
|
|
Before:
|
|
|
|
```
|
|
error: value is a set while a string was expected
|
|
```
|
|
|
|
After:
|
|
|
|
```
|
|
error: expected a string but found a set: { ghc810 = «thunk»;
|
|
ghc8102Binary = «thunk»; ghc8107 = «thunk»; ghc8107Binary = «thunk»;
|
|
ghc865Binary = «thunk»; ghc90 = «thunk»; ghc902 = «thunk»; ghc92 = «thunk»;
|
|
ghc924Binary = «thunk»; ghc925 = «thunk»; «17 attributes elided»}
|
|
```
