Make a function available under different names.

[00004]

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`.
