POLYMORPHISM AND GENERICS IN GO

Lately, Go has been getting a lot of flack for its lack of generics and parametric polymorphism. Whereas it doesn't have a specific language feature called "generics", generic type operations are very simple to implement. Here is a simple implementation of a generic collection type in Go demonstrating how it's done. Essentially, the type interface{} acts as a placeholder for any type. By making use of the empty interface, you can pass any type to a function much like you can in dynamically-typed languages.

Edit: Thanks to https://gist.github.com/mfenniak and https://gist.github.com/dominikh for pointing out that the add() function was equivalent to go's built-in append()

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
