Understand it, then run it
Go 1.27 adds generic methods. Before this, only functions and type definitions could have type parameters. Now a method on a concrete type can also be parameterized, so you can write a method that works for any element type. For example, a linked‑list type can expose a Map method that turns a list of int into a list of string without writing a new function for each pair of types.
