Make a function available under different names.

[00004 via Digitalmars-d-learn]

Let's say I have these two functions:
They have duplicate functionality.
```
string getExecutableNameFromMainFunction(string[] arguments){
        write("Executable_Name: " ~ arguments[0] ~ "\n");
    write("Debug mode is enabled.\n");
        return arguments[0];
}

string printExecutableNameFromMainFunction(string[] arguments){
        write("Executable_Name: " ~ arguments[0] ~ "\n");
    write("Debug mode is enabled.\n");
        return arguments[0];
}
```

How can I easily and in simple way make 
`printExecutableNameFromMainFunction` as function
where `getExecutableNameFromMainFunction` would share 
functionality or simply point to 
`printExecutableNameFromMainFunction`.
