in reply to Refactoring

I was wondering if it was just me... These types of changes aren't at all what I think of when I hear the term "refactoring". At the least, these would be at the very bottom of the scale.

To me, refactoring a program is like refactoring in math. In math, refactoring could be used to change (x^2-2x-3)(x^2+2x-3)
to (x^2-1)(x^2-9)
So I tend to think of refactoring as redesigning the boundary between the pieces that make up your program, often allowing code that is repeated to be removed.

I have a hard time coming up with good specific examples as refactoring is usually rather complex in my book. Some rather lame examples might be taking a handful of global variables and putting them into an object or changing a subroutine that takes a ton of arguments into one that takes a hash of options where most of them are optional with good defaults so most calls no longer need to specify them.

I guess the examples given so far just seem too trivial. (:
