Go language does not support method overloading

Go language does not support method overloading. The Go language does not support overloading in order to keep the language simple. Now the Go language can be embedded in C language code and compiled directly, or it can be compiled into a dynamic library or a static library for calls from other languages; without overloading, there are fewer obstacles to hybrid programming.

The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.

The above is a screenshot of the FAQ in the official Go language documentation. It seems that the question of why Go does not support overloading has troubled many developers. Many people asked questions, and the Go language official gave the above answer.

In the above answer, there is this sentence: Experience with other languages ​​told us that having a variety of methods with the same name but different signatures was occasionally useful but that it could also be confusing and fragile in practice.

The article says: Experience from other languages ​​tells us that having various methods with the same name but different signatures is sometimes useful, but can also be confusing and fragile in practice.

In addition, Go officials went on to say: In Go's type system, matching only by name and requiring type consistency is a major simplification decision.

The official blog finally said: Regarding operator overloading, it seems to be more convenient. But again, things would be simpler without overloading.

We can probably tell through a few short sentences. There is actually no profound reason why the designers of the Go language did not implement overloading in Go. It is the core principle: Keep Go simple enough. Don't underestimate this simple description. In my opinion, insisting on making Go simple enough requires Go designers to exercise great restraint.

Summary:

The Go language does not support overloading in order to keep the language simple. Now Go language can be embedded in C language code and compiled directly, or it can be compiled into a dynamic library or static library for calls from other languages. Without overloading, there are fewer barriers to hybrid programming.
