That's certainly the fashion in object-oriented code.  I may be
showing my ignorance, but I'm afraid I don't see the benefit in doing
that for a single uncomplicated global variable.  An object with
complicated semantics, or semantics that must be constrained and
checked for validity, of course -- that's one of the points of
object-oriented code, and it's a very useful technique.  But a simple
count, say, or a string that's unrelated to anything else?  Why not
require getters and setters for that are visible for more than 50
lines, say, or for all variables?
