Precisely the reason I use the Java approach to C++ global variables,
i.e., I try to make everything a member of some class, including global
variables, which can be declared as public static members of classes.
Thus any use of a "global" variable requires a classname prefix.


C++ namespaces provide similar functionality.


For languages that don't have classes or namespaces, like C, I
use a unique affix on related names. Not as good a solution,
true, but usually sufficient.
