What is an alias in the context of the rune programming language?

In the Rune programming language (a language focused on safety and extensibility, often used in the context of Go), an alias is a mechanism for creating aliases for types or modules.

An alias allows you to use a shorter or more convenient name instead of the full name of a type or package, which improves readability and simplifies the code.

Example of an alias for a type:

alias MyInt = int

fn main() {
    var x: MyInt = 10
    print(x)
}

Here, MyInt is an alias for int. Similarly, aliases can be created for modules or functions to simplify import and usage.
