If Go generics support typeclasses, things will be much better now. At least custom generics and built-in generics will be unified harmoniously. Now, the manners of type argument passing with the built-in `new` and `make` function and custom generic functions are different. The inconsistency increases the load of cognition burden in Go programming.

It is pity that Go generics designer never expressed the intention to unify custom generics and built-in generics.
