如何导出名称以使其可全局访问？

Question

I want to export a function from my package so that I can use it without typing a package name before it, how to do that?

import "mypackage"

func main() {
   mypackage.myfunc()    <-- that's what I have already
   myfunc()              <-- that's what I need
}

You can use one of the followings:

import (  
    .     "mypackage"                           // without a name  
    mp    "my/other/package"                    // rename
    _     "my/totally/diffrent/package"         // import a package solely for its side-effects (initialization)
)

Obviously, this pattern is not recommended since it can cause name conflicts with other packages.
