Yeah, I thought the same.

I now realise the better test of 'var' would be to compare it to how many times it's not used. That is count the times that 'var myClass = new MyClass()' is used v 'MyClass myClass = new MyClass()'. But my regex skills aren't good enough for that and I'm not even sure if you can do it purely in a regex?

Also I imagine that 'var someNumber = 1' is used less that 'int someNumber = 1', but again, I'm not sure how to do the regex? I certainly only use 'var' when the same word is on both sides of the '=', so not in the case of int/double/decimal etc.

I still use var in that scenario, because if you need different types you have to suffix numbers with an identifier anyway:

    var i = 1; //int
    var j = 1f; //float
    var k = 1m; //decimal
    var l = ""; //string
    var m = ''; //char

There are a few more for numeric types:

  var integer = 1;
  var long = 1l;
  var float = 1f;
  var double = 1d;
  var decimal = 1m;
  var unsignedInteger = 1u;
  var unsignedLong = 1ul;

Yeah, I know you can do that, but I can never remember which suffix is which ;-)
