Hello! I'm interested in working on this. Agreed that tweaking the existing `ScalarUDF` code would be ideal as it would be least breaking. However, after poking around a bit, I have some concerns: - How do implementers define a signature for a UDF that takes one or more lambdas? Do we just skip type checking of lambda arguments? How does this affect the ordering? - How should one map lambda function arguments to concrete values in the body? If the function only operates on a list, this becomes easier to express. A more prohibitive interface certainly seems like it would help implementation here, albeit at the expense of consumer flexibility. Any thoughts/feedback would be much appreciated.
