You're confusing something here, and I can't tell what it is.  The
variable $funcRef is NOT global -- it is lexically scoped (because you
used my() on it).  It is not visible OUTSIDE the scope that you declared
it in -- but it IS visible inside smaller scopes, like the one of the
callTheReferredFunc() function.
