Martin,
Thanks for the brilliant coding on this.. I wanted to *figure out* how to code it more than I really wanted the features :) I learned a ton of new technique just studying your code over the last couple days. I'm coding a version for myself and thought of an interesting application of your code...
It would be trivial to add another version of #pre that would specify and validate parameter types. E.g.
params(String, Integer, Proc)
Now, imagine doing this for two methods of the same name with different parameter types-- method overloading in Ruby!
Not exactly the most useful addition given how simple it is to check types, but, theoretically, it's interesting :)
What do you think?
Very useful even if I prefer the Eiffel syntax which I found more expressive: 'require' for 'pre', 'ensure' for 'post'.
Why was there no follow on bankruptcy then? The bailout of AIG FP went to (wow power leveling) hedge funds that bound credit swaps on Lehman failing or others betting on rating (wow power leveling) declines. AIG has drained over 100 billion from the government. Which had to go to (wow power leveling) those who bet on failures and downgrades. Many of whom (power leveling)were hedge funds. I-banks that had offsetting swaps needed the money from the AIG bailout or they would have been caught. Its an (wow powerleveling) insiders game and it takes just a little bit too much time for most people to think (wow gold) through where the AIG 100 billion bailout money went to, hedge funds and players, many of whom hire from the top ranks of DOJ, Fed, Treasury, etc. ZHANG XIAO CHEN

What are the main reasons for people using ruby ? I've dabbled in many languages but not sufficiently enough in Ruby. Is there a best way to get to grips with this language ?
