Superpowered keyword args in Haskell
- The Keyword Args Pattern
- The pattern I will describe here solves the argument transposition issue and reduces specifying “I don’t care” for very general function call. The trick, if you can call it that, is to stuff all of those parameters into a data type, then make that data type defaultable and allow overriding its fields to deal with special cases like filters and sorting. It reminds me of Keyword Args in languages like Python, so I’ll refer to this as the Keyword Args Pattern.
- then the Keyword Args pattern might work for you.
