There is still nothing built-in to provide the exact functionality you describe. However, an alternative to using require it to use the .load command within the REPL, like such:
.load foo.js
It loads the file in line by line just as if you had typed it in the REPL. Unlike require this pollutes the REPL history with the commands you loaded. However, it has the advantage of being repeatable because it is not cached like require.
Which is better for you will depend on your use case.
Edit: It has limited applicability because it does not work in strict mode, but three years later I have learned that if your script does not have 'use strict', you can use eval to load your script without polluting the REPL history:
var fs = require('fs');
eval(fs.readFileSync('foo.js').toString())

Note the difference in the outputs of the above two lines. The Node REPL printed undefined after executing console.log(), while on the other hand, it just printed the result of 5 === '5'. You need to keep in mind that the former is just a statement in JavaScript, and the latter is an expression.
