my() and our() have the same scoping so they will behave the same. my()
variables are scoped from the point they are declared up to the end of the
current file/block. Since your variable is not inside a block it is visible
throughout the rest of the file. By the way, you shouldn't use $a or $b as
they are "special" variables.
