The thing is that m is a reserved word, since you can use it to tell that what comes after it plus a dot is variable, even though a field may have the same name. Like if you have opened a table with a field called XX with a value of 5, and a variable called XX with a value of 10. Now you see the following:

This does not prove in any way that the following claim is right
