Added the obj.each{} syntax, which will execute block for each element inside the self object; For hashes, the argument passed to the block will a [key, value] array;
Example:
	"sidef".each { |chr|
	    say chr;  # prints each character
	};
	["hello", "world"].each { |item|
	    say item; # prints each item
	};
	:("key" => "value").each { |key,value|
	    say "KEY: #{key}; VAL: #{value}";
	};

Added the Number.times{} method;
	Example:
	5.times { |i|
	   say "Hello! (#{i})"	# prints: "Hello (1)", "Hello (2)", ...
	}
