Go 1.27 now supports generic methods: a method declaration may declare
its own type parameters. This widely anticipated change allows adding
generic functions within the namespace of a particular data type where
before one had to declare such functions with a scope of the entire
package.

A key in a struct literal may now be any valid field selector for the
struct type, not just a (top-level) field name of the struct.

Function type inference has been generalized to apply in all contexts
where a generic function is assigned to a variable of (or converted
to) a matching function type.
