-"""Generics support via go_generics.
-
-A Go template is similar to a go library, except that it has certain types that
-can be replaced before usage. For example, one could define a templatized List
-struct, whose elements are of type T, then instantiate that template for
-T=segment, where "segment" is the concrete type.
