String.prototype.interpolate = function (o) {
    return this.replace(/#\{(.+?)\}/g, function ($0, $1) {
        with (o) {
            return eval($1);
        }
    });
}

you should replace eval($1) with something smarter because it opens a big security hole.

Agreed. At the time it was just a really quick idea I had for Ruby-like string interpolation. What would you replace eval($1) with to make it more secure? I guess you could start by processing the expression for assignments or function calls so the expression can only contain an R value (without method calls).

Ah, forget I asked. Just noticed your fork. Thanks for the work!
