// In the following code sample, invoking the curried function will always
// return a function until all arguments are satisfied, at which point the
// original function is invoked, returning its result. This means that all
// function arguments are required, which also allows the function to be
// called either like foo( 1, 2, 3 ) or foo( 1 )( 2 )( 3 ). This also means
// that if any argument is omitted, the original function is never invoked.

//I do not understand what the "null," part buys.
//Has to do something with scope(?), but at least in Firebug, 
//I can see foo inside the string being evaled.
