So-called 'treeshakers', that throw away functions that aren't called by
other functions, are examples of 'user visible GC', since the user could
conceivably call these functions from top level at any time.
You basically have to do something reasonable and simple, so that the
user can understand intuitively what is going on. A simple rule is
better than a complex but 'better' rule, since the poor user won't have
a prayer of intuiting the more complex rule.
