How "OO" is it? In Ruby, for better or for worse, everything is an

(if not prudent) to do pretty much anything.
How does it support cross-cutting concerns? Lately, I have been
missing the ability to do Aspect-oriented programming in Ruby. For
example, I want to HTML-escape the return value of any model getter
which is in the call stack of a view. We ended up doing it manually,
for every field in every view. When I started rambling about how you
could do that sort of thing with 5 lines in AspectJ (and never have to
worry about forgetting it for future fields), I just got blank
stares...
What about AspectR? Or metaprogramming? I'll be honest I haven't
looked too much at Ruby's metaprogramming model, but the
HigherOrderMessaging stuff I posted a while ago looked like it might
be able to handle something like that.

Hi all,
I was just curious, when you start learning a new language, what do
try and do first?
Here are some of the ones that I look at:
- looping (how do I do a for loop)
- if, then, else
- switches (do they exist?)
- object and array creation (what types are there and how do I do it)
In a sense this goes beyond just syntax and assumes that you (the
developer) already have some knowledge of how to program and are
familiar with OO.
