title: Writing Global Function in Go -- like append()
body: <p>The Question is simple - how can i implement a package independent global function in golang.</p>
  
  <p>ID, if i have a function in an package called core then from another package i need core.Function() to call that function. But i In go implementation there are some functions like - make(), append() for slice that can used without any import and within any package directly. If i wanted to write function like this what is the way of doing this? how can i write any function like this if it is possible. </p>
