Do you use 'this' in front of instance variables?

Question

When accessing instance variables or properties of a class from within the class itself, do you prepend them with \"this.\"?

Answer 1

Yes, if I see this. I'm sure it is local and I do not need to look any further. If it isn't prefixed with this. (or maybe '_') I have to check if it is declared locally or in an ancestor or if it's a parameter or ...

All these checks take a little more time during debugging...
