Pythonでは条件によってブロックをスキップするような構文がない

	@on('POST', '/foobar')
	def do_post(self):
	do_something1()
	do_something2()
	## 残念ながら Python ではブロックをスキップする機能が
	## ないのでこれは使えない
	with invoke('new_cool_feature_name'):
	old_feature1()
	old_feature2()
	## なので、decoratorをhiger order functionの

My favorite nonblocking read() API in Ruby

	class IO

	##
	## Easy-to-use nonblocking read()
	##
	## * returns non-empty string when data exists
	## * returns empty string when data not exist
	## * returns nil when EOF
	##

Local variable is not initialized in C++

	#include <iostream>

	int fn() {
	int x;
	return x; // returns uninitialized local variable
	}

	int main(int argc, char*args[]) {
	//std::cout << "Hello\n";
	std::cout << fn() << "\n";

kwatch / ex2.cpp

C++ compiler warns uninitialized local variable of int, but not of object.

	#include <iostream>
	#include <string>

	void fn() {
	int x;
	std::string s;
	std::cout << x; // warning: variable 'x' is uninitialized when used here
	std::cout << s; // (no warnings due to default constructor)
	std::cout << "\n";
	}
