Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!

/**
 * Bounded priority queue trait that is intended to be mixed into instances of

 * Scala are unbounded. This trait modifies the original PriorityQueue's
 * enqueue methods such that we only retain the top K elements.
 * The top K elements are defined by an implicit Ordering[A].
