A Match-Like DSL for Deep Immutable Updates
match is very convenient for deconstructing data and accessing values deep within a data structure, but it is not useful for making changes to that data structure. In this talk, I’ll present a DSL that looks like match, but allows you to perform immutable updates on the target value using pattern variables to specify where an update should occur. I’ll also talk about optics, which are the abstraction powering these immutable updates.
