Here's my try: >> ([2,1,4].map {|x| (x.is_a? Integer)}).reduce {|x, result| x and result} => true >> ([2,"a",4].map {|x| (x.is_a? Integer)})...

So if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able t...
I'm wondering if there is built-in .NET functionality to change each value in an array based on the result of a provided delegate. For example, if I had an array {1,2,3} and a delegate that returns the square of each value, I would like to be able to run a method that takes the array and delegate, and returns {1,4,9}. Does anything lik...
