Incomplete implementation of partial functions #95
Description
We have some problems wrt. to partial functions:
- partial functions keep the signature of the base function (see Incorrect each function signature validation #79)
- bug in , arg.value is char and comparison will always be false
- partial function derived from custom function (see Custom function pipe error #83)
- we re-use the base function for partial functions (see incorrect result when $map($, $append(?)) #86)
- there are some TODOs which we did not yet implement because of the lack of unit test coverage ( )
