My question is:  Are strings like " is:" volatile or not?
When you say p2 = " is:", are you sure that the string will remain in
memory or the optimizer will decide to put something else there since
the string is basically a constant used only once??
I also have the idea that if you say
        p1 = "abc";
        p2 = "abc";
p1 and p2 will have different value, since the strings are not the same
(they have the same contents, but physically should be different).
Is that a right assumption?
