Is it possible to apply the same context to many functions?

Is there a way to bind the same 'this' context to different functions?

var obj = {'a':1, 'b':2 };    

init.call(obj);

function init()
{
  func1.call(this);
  func2.call(this);
  func3.call(this);
  etc...
}

Preferred syntax:

function init()
{
  // each function should use this.
  func1();
  func2();
  func3();
  etc...
}

Not really a problem per se, just syntactic sugar and DRY; thanks in advance.

Edit: Thanks to Barmar, I came up with this:

[ func1, func2, etc... ].forEach( function(func){ func.call(this); }.bind(this));

You could write a function that does it:

function callAll() {
    var funcArray = Array.prototype.slice.call(arguments);
    for (var i = 0; i < funcArray.length; i++) {
        funcArray[i].call(this);
    }
}

Then you can do:

callAll.call(obj, func1, func2, func3);
