On: Why teach with Ruby?

[gmac]

I figured that Ruby must have similar functionality to Python's dir()

Sounds like you wanted

   'x'.methods
    => [:<=>, :==, :===, :eql?, :hash, :casecmp, ... ]

or the more focused

   'x'.methods - Object.methods
    => [:casecmp, :+, :*, :%, :[], ... ]

?

Yup - that's exactly what I was looking for. Awesome.

The question is why Python calls it "dir" when you just want to see a list of the object's methods...
