No, it doesn't.  (This is implicitly apparent from the type signature
of opt_internal_int() - it returns an int, not an int&, so there's no
way for an assignment to the C++ variable "var" to affect any other value.

There is no simple mechanism to reflect changes to a C++ variable into
a Bro policy script variable.  To do so, you have to locate the corresponding
Bro variable and invoke the Assign() method on it.
