Have you ever experienced the software becoming bigger and less maintenance?
In such a case, I think it is important to divide the code, make it easy to change, and make code easier to read.

For that reason, I thought the Interface was useful, and I made a module called Function::Interface.

Function::Interface checks the arguments and return type of the function at compile time.
For example, you can write like this:

package IFoo {
    use Function::Interface;
    use Types::Standard -types;
    fun hello(Str $msg) :Return(Str);
}

package Foo {
    use Function::Interface::Impl qw(IFoo);
    use Types::Standard -types;

    fun hello(Str $msg) :Return(Str) {
        return "Hello! Pittsburgh! $msg"
   }
}

It's strange but interesting!
