Shapeless

Shapeless is a library in programming, specifically in Scala, that makes working with data structures more flexible and less verbose. Traditionally, handling different types of data requires defining specific classes or structures, which can be cumbersome. Shapeless allows programmers to manipulate and combine data generically, without needing predefined schemas, by using concepts like "heterogeneous lists" and "generic programming." This means complex data can be processed, transformed, or extended more easily and with less boilerplate code, enabling more adaptable and maintainable software, especially when dealing with diverse or evolving data formats.
