String.format()

Why not use the same format as util.format()? Like:

"Show something here: %s, or here: %s".format(1, 2);
  \=> "Show something here: 1, or here: 2"

Originally picked up the habit from C#, what you're suggesting doesn't allow stuff like:

var body = "<{0}>" +
"<{1}>{2}</{1}>" +
"</{0}>".format("body", "h1", "Hello World!");

As an example.

The node convention is more limited, true, but also more familiar. Also: less typing of those pesky curly brackets.

In the prototypes library I try to put only things that have wide use already, not to invent new ways of doing things. (Which perhaps I should be doing.) I have often felt the need of formatting a string without importing util so I think your PR is a great opportunity to do it, but if the format is too alien I fear it is not going to be used as much except by people already familiar with C#.

Were you thinking something like this?

var body = "<%0>" +
"<%1>%2</%1>" +
"</%0>".format("body", "h1", "Hello World!");

Hmmm, better, but still not the format that Node.js uses. Why not adopt it
as is? Granted, there may be some repetition in parameters, but I think it
can even be less confusing.

A few weeks have passed, if you don't mind I will implement it as suggested, which is a shallow wrapper over util.format().

Reimplemented with the same conventions as util.format() in 0.3.1, closing. Thanks!
