This bit of ruby should take care of it

    HashMap = HashTable = Map = Table = Dictionary = Hash

And if you're feeling adventurous,

    Object.send :remove_const, :Hash

[agscala]

Please never, ever do this

[DanWaterworth]

If doing this is such a bad idea then why is it so easy?

[jlgreco]

If doing:

  #define BEGIN {
  #define END }

were such a bad idea, then why is it so easy?

[DanWaterworth]

Maybe the language is poorly designed.

[jlgreco]

Or maybe the connection between being able to do something and it being a good idea to do something is just in your head.

[DanWaterworth]

In my experience, making obviously bad things difficult or impossible improves reliability. This idea certainly resides within my cranial cavity, but that doesn't necessarily make it wrong.

I approve of this. Don't listen to that other guy. This should be standard.

One addition though:

    Cocktionary = HashMap

"Dictionary" never really made sense.
