var foo = bar || 1; // 1
var bar = 2;

RestSharp JSON Parameter Posting
...t do
request.RequestFormat = DataFormat.Json;
request.AddBody(new { A = "foo", B = "bar" }); // uses JsonSerializer

...t i = 42;
std::string s = sstr( "i is: ", i );

Foo x( 42 );
throw std::runtime_error( sstr( "Foo is '", x, "', i is ", i ) );

Non greedy (reluctant) regex matching in sed?
...uence of digits) Live demo:
$ sed -r 's/([0-9]+).*|./\1/g' <<< 'foo 12 bar 34'

This might work for you:
function foo() { bar(); }
function bar() { console.log(bar.caller.name); }
running foo() will output "foo" or undefined if you call from an anonymous function.
It works with constructors too, in which case it would output the name...

foo = u'Δ, Й, ק, م, ๗, あ, 叶, 葉, and 말.'
f = open('test', 'w')
f.write(foo.encode('utf8'))
f.close()
When you read that file again, you'll get a unicode-encoded string that you can decode to a unicode objec...
