- Consider functions with only one value on the rhs as variables
- Applied composition: `(f . g) <param>` -> `@function.call`
- View patterns
- `@field` in record update expression
- type_tuple and type_list as variables
- quantifier for `exp_apply (<rhs>)+ (variable)`
- type_tuple and type_list as variables
- Treat signatures with only one value on the rhs as variables
(except for `IO a`) -> Fixes#5505.
- Remove redundant anchors from signature function queries.
- Move signature function queries to give them higher priority
- Scoped function types
- Add signature query to function with parameters query
